access-list 101 deny ip any host 162.159.128.233

! Block Discord domain names
ip domain list discord.com
ip domain list discord.gg
access-list 101 deny ip any host discord.com
access-list 101 deny ip any host discord.gg

! Apply the access list to the appropriate interface
interface GigabitEthernet0/1
 ip access-group 101 in

For comprehensive lists of Discord servers and IPs to block, refer to resources such as:

Creating Whitelists for Approved Users

For users with approved access, create specific firewall rules to allow traffic. This can be done by setting up a whitelist:

! Allow approved users to access Discord
access-list 102 permit ip host approved_user_ip any

! Apply the whitelist access list to the appropriate interface
interface GigabitEthernet0/1
 ip access-group 102 in

C. Proxy Servers

Filtering Traffic

Utilize proxy servers to filter and control web traffic. Proxy servers can block access to Discord by filtering requests to known Discord domains. This ensures that only approved traffic passes through the network.

Overview of Passkeys

Passkeys represent a paradigm shift in online security, reimagining user authentication to be both more secure and user-friendly. A digital successor to the traditional password, passkeys offer companies a way to prevent phishing attacks, since credentials cannot be reused across services. They are pivotal in simplifying the login process while fortifying security.

What are passkeys?

Passkeys are a type of multi-factor authentication that leverage a cryptographic key pair—a public key that is stored on the server and a private key kept securely on the user’s device—to authenticate access. This method is deemed more secure and convenient compared to passwords, as it reduces vulnerabilities like credential stuffing and phishing. Passkeys remain device-bound, which means the private key never leaves the user’s device, thwarting interception attempts and ensuring that even if the public key is compromised, accounts remain protected.

How do passkeys work?

The operation of passkeys hinges on public key cryptography. When a user attempts to access a service, the server dispatches a challenge to their device. The device responds by using its stored private key to sign the challenge. This signed response is then relayed back to the server, which verifies the signature using the public key. If the signature is correct, access is granted. Throughout this process, passwords are never required, thereby diminishing the chances of user credentials being intercepted or stolen. Biometric features, such as facial recognition or fingerprint scanning, are frequently integrated to confirm the user’s identity before the device signs off.

Benefits of using passkeys in corporate environments

The integration of passkeys into corporate environments poses a myriad of benefits:

Enhanced Productivity: Passkeys eradicate the inconvenience of remembering passwords, which allows employees to focus on core business tasks without interruption for password recovery.
Lower IT Costs: With device syncing and cloud storage, employees can resolve access issues independently, diminishing the number of helpdesk tickets related to password resets.

User Experience and Accountability: With passkeys, employees enjoy a seamless login experience across various devices and platforms, which also enables precise tracking of actions on individual user accounts.
Resilience to Phishing: The structure of passkeys inherently resists phishing schemes, which substantially reduces the looming threat of such attacks in corporate settings.

In summary, the rollout of passkeys in the corporate sphere is poised to strengthen security protocols while promoting a more efficient and user-friendly authentication landscape. As technology giants like Apple, Google, and Microsoft endorse this innovative method, the adoption of passkeys is slated to become a gold standard for enterprises aiming to fortify their cybersecurity architecture and enhance operational efficiency.

Understanding Multi-Factor Authentication

In today’s increasingly digital corporate landscape, ensuring the security of sensitive information is paramount. One of the pivotal strategies for bolstering identity security in enterprise environments is Multi-Factor Authentication (MFA). MFA isn’t just about adding layers of security; it’s about smartly leveraging various credentials to create a more robust defense against unauthorized access.

What is multi-factor authentication (MFA)?

Multi-factor authentication (MFA) is a security mechanism that requires users to verify their identity by presenting multiple credentials before gaining access to a system. Instead of solely relying on passwords, MFA combines at least two of the following authentication factors: something the user knows (like a passcode), something the user has (such as a security key or smartphone), and something the user is (biometric verification, like a fingerprint or facial recognition). By integrating MFA, organizations can dramatically reduce the odds of a security breach, as gaining access requires circumventing several security layers rather than just one.

How can passkeys be used as part of MFA?

Passkeys are a relatively new but powerful player in the MFA arena. Functioning as cryptographic key pairs, they securely encrypt data and guarantee that the user is who they claim to be without the pitfalls of traditional password-based systems. In the context of MFA, passkeys are the possession factor – something the user has. Because the private key is stored on the user’s device and never shared, passkeys significantly mitigate the risk of credential attacks. When used together with a biometric factor or PIN (something the user is or knows), passkeys embody the principles of MFA while offering a consistent and user-friendly authentication experience.

Advantages of using passkeys for MFA in corporate environments

The adoption of passkeys within corporate MFA systems presents a range of advantages that extend beyond traditional security benefits:

Enhanced Security: Passkeys are secure by design, featuring lengthy, unique, and randomly generated strings that are incredibly challenging for bad actors to compromise.
Reduced Risk of Phishing: Due to their cryptographic nature, passkeys are resilient to credential stuffing and phishing attacks, as they cannot be reused or easily intercepted.
Ease of Implementation: The integration of passkeys into MFA systems is supported by major technology providers, simplifying deployment in corporate settings.
Non-repudiation: Passkeys offer an audit trail, linking actions directly to individual users, which helps with compliance and incident analysis.
Streamlined User Experience: Passkeys eliminate the frustration associated with forgotten passwords, thus improving productivity and user satisfaction.

In essence, passkeys as part of MFA in enterprise settings not only amplify security but also promote a more intuitive and frictionless user experience, which is instrumental in nurturing a security-conscious culture without sacrificing efficiency.

Exploring Facial Recognition as a Passkey Option

In corporate settings, the quest for robust security measures that also elevate convenience is relentless. Facial recognition emerges as a shimmering beacon in this realm, offering a way to both solidify security protocols and streamline access processes. By incorporating facial recognition technology, passkeys not only transcend the traditional password paradigm but also reimagine user authentication through a seamless, passwordless experience.

Introduction to facial recognition technology

Facial recognition technology rests on the cutting edge of biometric verification, providing a sophisticated yet user-friendly method for identity confirmation. When paired with passkey technology, it bolsters the security framework, enabling users to gain access to systems, websites, and apps with just a glance. Notably, Microsoft’s Windows Hello presents a shining example of this technology in action, advocating for a phishing-resistant login that employs facial recognition, eliminating the dependency on recollectable passwords. The harmonious marriage between passkeys and facial recognition sets the stage for a future where traditional authentication methods gracefully bow out, making room for a more secure and convenient approach—echoing the industry’s pursuit of advancing user-centric security measures.

Using facial meeting as a passkey in corporate environments

The implementation of facial recognition as a passkey within the corporate landscape brings forth a plethora of benefits. This merger of technology offers a reciprocal reinforcement where the reliability of cryptographic key pairs complements the uniqueness of biometric data, yielding a fortified bulwark against unauthorized entry. Such synergy not only deters phishing attempts and mitigates password breach incidents but also refines the user experience to an impeccable standard. Employees are alleviated from the burdensome task of password memorization and management, thus enabling a swift and uninterrupted transition between tasks. Moreover, by streamlining the authentication process without compromising security, facial recognition passkeys promise a reduction in IT-related expenditures, tipping the scales toward operational efficiency and cost-effectiveness.

Security considerations and challenges with facial recognition as a passkey

While the fusion of passkeys and facial recognition represents a monumental leap in access management, it is imperative to scrutinize any potential security implications and challenges. Passkeys, erected upon the foundation of public and private cryptographic keys, must be vigilantly protected, with the sanctity of the private key being paramount. The utilization of FIDO standards, embedded in strong cryptographic principles, endorses the integrity of passkey systems that integrate facial recognition. However, the accuracy and reliability of such biometric systems, as well as concerns around potential privacy invasions and spoofing, must be cautiously considered and mitigated through ongoing improvement and rigorous standards compliance. Despite these hurdles, Google’s initiative to eschew passwords in favor of biometric authentication heralds a transformative shift, promising a harmonious balance of enhanced security and user-centric convenience, tailor-made for the digital age.

Implementing Access Management with Passkeys

Access management serves as the gatekeeper in corporate settings, dictating the realms of digital resources that employees can traverse. It determines the level at which individuals have the privilege to engage with data across an array of devices, such as any device, strictly managed ones, or ones under heightened supervision. Managing the distribution and syncing of critical components like passkeys is instrumental in safeguarding corporate data. This function is flexible, allowing for configurations that suit the security topology of a company, whether passkeys are accessible on any device, are restricted to managed devices, or are limited to supervised appliances only. The architecture of device management servers is fundamental, as they must endorse the intricacy of access management to ensure that work-related passkeys are synchronized exclusively with company-managed hardware.

Role of Passkeys in Access Management

In the labyrinth of corporate cybersecurity, passkeys signify a transition from broad to surgical access controls. Administrators now have the dexterity to assign specific keys to users or groups, thereby defining access limits to company resources with precision.

Furthermore, the shift towards passkeys in corporate landscapes seems inevitable as more enterprises recognize the drawbacks of password-dependent systems and embrace the gold standard of security that passkeys represent.

Unique security challenges in enterprise environments

The pivot to passkeys in corporate settings must confront an array of unique security conundrums. Predominantly, the present lack of support for Strong Customer Authentication (SCA) by passkeys poses compliance challenges within heavily regulated industries. Enterprises must juggle the implementation of passkeys with meeting the stringent stipulations of regulatory frameworks such as the General Data Protection Regulation (GDPR) and the Health Insurance Portability and Accountability Act (HIPAA).

Traditional password-based authentication is a breeding ground for vulnerabilities and unauthorized access, a significant pain point for enterprises. The human contingent often emerges as the weakest security link, with users historically defaulting to easily decipherable passwords that are frequently recycled across platforms. This human tendency increases the susceptibility to cyber-attacks manifold, thereby amplifying the urgency for more robust authentication technologies. Security teams, alongside Chief Information Security Officers (CISOs), are tasked with meticulously vetting authentication methods and ensuring they align neatly with organizational controls.

How passkeys can address these security challenges

Passkeys provide a secure, systematic solution to the intricate challenges of enterprise authentication. Reducing the reliance on passwords eliminates a significant vector for data breaches and unauthorized ventures into corporate data. Passkeys’ resistance to phishing attacks lies in a simple yet profound principle—they do not revolve around shareable secrets. Consequently, the risk of crucial information being intercepted or duped is significantly lowered.

Accountability is heightened in a passkey-centered authentication framework. Each action can be precisely mapped back to its performer, aiding in the rapid unraveling of security incidents or violations of policies. Moreover, the rise of remote and hybrid work models magnifies the value of passkeys.

Case studies of passkey implementation in enterprise environments

An examination of real-world applications reveals the tangible benefits of integrating passkeys into enterprise settings. Organizations that have woven passkeys into their cybersecurity fabric have observed a marked enhancement in user accountability, with each transaction or action being attributable to a specific user. This attribution is not only beneficial for routine audit trails but also proves invaluable when a swift response is critical—during a data breach, for instance.

Remote work, a fixture of contemporary corporate culture, gains a fortified layer of security through implemented passkeys. The assurance that sensitive systems remain impenetrable to all but explicitly permitted personnel is a testament to the efficacy of passkeys in modern environments. Comprehensive policies and practices encompassing password management, access delineation, MFA, SSO, and adoption of password managers are pillars of effective passkey implementation.

As cybersecurity strategies evolve, the synergy between passkeys and SSO-enabled applications becomes noteworthy. Companies have been adopting passkey-supported password managers to streamline access management, concurrently enhancing identity security and user experience. This alliance illustrates the potential of passkeys to redefine authentication, carving a path toward a user-friendly and secure enterprise landscape that transcends traditional password dependencies.

Key Pair and Security Key: Strengthening Passkey Authentication

Passkeys are revolutionizing enterprise security by leveraging key pairs—a public and a private key, which work in tandem to fortify authentication processes. When a user registers with a service, they generate a key pair and the public key is sent to the service to be stored on its server. The private key, which is never shared or transmitted, is securely stored on the user’s device. This mechanism improves security by replacing vulnerable passwords with cryptographic credentials that are unguessable and unique to every interaction, thereby setting a new precedent in secure access management in the corporate domain.

What are key pairs and security keys?

Key pairs are at the heart of passkey technology. A public key encrypts information, which can only be decrypted by the corresponding private key. This customization of keys means that even if a public key is intercepted, unauthorized entities cannot decrypt the information without the private counterpart. Passkeys elevate security by binding these cryptographic keys to a user’s device—typically a smartphone or hardware token—using protocols underpinned by FIDO Authentication standards. This secure storage ensures that only authorized personnel can gain access to enterprise systems, and the decryption capabilities are safeguarded from potential cyber threats.

How do key pairs and security keys enhance passkey authentication?

Key pairs and security keys heighten passkey authentication by creating a system that is inherently resilient to phishing, pretexting, and other social engineering attacks. Since the private key is device-bound and not stored on any server, hackers are left with no actionable data, even in the unfortunate event of a server breach. Passkeys are service-specific, removing the vulnerability of reused credentials across multiple sites—a common pitfall that often leads to cascading security breaches. By effectively eliminating complex passwords, key pairs streamline the user experience, while simultaneously bolstering security, illustrating a win-win scenario for businesses and users alike.

Examples of key pair and security key implementation in corporate environments

In the corporate sphere, the implementation of passkeys with key pairs results in a multifaceted enhancement of security protocols. Biometric checks such as fingerprints or retina scans serve as a validation method without exposing biometric data—it stays within the user’s device, with only a signal of successful verification reaching the server. With the future direction towards passkey and password manager collaboration, passkeys will likely be stored in secure vaults provided by password management solutions, further solidifying corporate data protection.

Companies can supplement current password policies by implementing passkey-enabled systems that encompass:

Biometric authentication for swift and secure access
Robust password manager applications to support the transition and maintain rigorous admin controls
Continual compliance with evolving industry standards ensuring a resilient defense against unauthorized access

In summary, the synergy between key pairs and security keys within passkey frameworks presents an innovative leap in the realm of cybersecurity. As organizations embrace this advance, they lay the groundwork for a more secure, password-free future that promises not only improved protection but also a more streamlined authentication experience for users.

Summary

In today’s dynamic enterprise environments, passkeys are emerging as a robust solution to traditional authentication challenges. They mark a significant shift from passwords by enabling passwordless sign-ins, making use of convenient and secure methods such as Touch ID or Face ID. Passkeys are unique for each app or website, greatly enhancing security and offering a consistent user experience. With the capability to be stored on smartphones, users benefit from the flexibility of either having their passkeys synchronized across platforms via the cloud or tied to individual devices.

These cryptographic keys are designed to be phishing-resistant, mitigating common security issues like credential stuffing. They can be stored either on a user’s mobile device or a dedicated physical security key, providing a seamless authentication process. By leveraging cryptographic key pairs compatible with FIDO devices, passkeys not only bolster security but also streamline the user interface.

The adaptation of passkeys in corporate environments promises to reduce the frequency of password resets, thwart unauthorized access, and counteract credential attacks more effectively than traditional two-factor or multi-factor authentication methods. Passkeys are primed to become the industry standard, delivering additional security without compromising on user experience.

Just a quick reminder, at some point during each quarter, it is a good idea to enact a process to seek out and remove any end-of-life products in your environment. This is not only a best practice but a significant risk reduction measure as well. Make it an ongoing periodic process, and you’ve got a powerful weapon against threats and emerging issues stemming from end-of-life hardware, firmware, and software in your networks.

How to Search for End-Of-Life Products In Your Environment

The first step is to identify the devices, applications, and firmware that are no longer supported by their vendors. You can do this manually or with a tool. The next step is to determine which of those devices have been deployed in your network. Once you know where they are, you need to find them. There are several ways to search for these devices:

Use Network Inventory Tools

Network inventory tools such as Nmap and Nessus will allow you to scan your entire network to locate all of the devices on your network. These tools will also tell you what operating systems and versions of software/firmware are running on the device. If you’re using a vendor-specific tool, you’ll be able to see if there are any known vulnerabilities associated with the product in many cases.

Talk to Device and Application Owners

If you don’t already have a relationship with the owners of the devices and applications, then you should start building one now. It’s important to get to know the people who own the devices and applications so that you can ask questions about how they use the devices and applications. You may even want to consider getting an end-of-life security policy together for the organization so that you can make sure everyone understands the risks of end-of-life components.

Once you have discussed the issues with the owner, remove the component if possible. Otherwise, add it to a list of components to look for workarounds or replacements. Many organizations that can’t manage to replace an end-of-life component either place it in a low trust network zone, front-end it with firewalls or ACLs, and increase monitoring and detection of the assets involved. Of course, the component should be reviewed quarterly until it can be removed from service.

Doing this process every quarter will increase your networks’ overall stability and trust worthiness, plus reduce risk and management headaches. It’s well worth your time and an effective part of an overall risk management strategy.

3 Common Challenges Implementing Multi-Factor Authentication

Posted on January 26, 2022 by Brent Huston

Multi-factor authentication is becoming increasingly popular among businesses and consumers alike.

However, many organizations struggle to implement the technology successfully.

Here are three challenges organizations face when implementing multi-factor authentication.

1. Lack of Awareness

Many organizations don’t understand what multi-factor authentication is or why they should use it.

They think it’s too complicated, expensive, or unnecessary.

This misconception leads to a lack of awareness about the security risks posed by weak passwords and phishing attacks.

2. Security Concerns

Some organizations believe that multi-factor authentication adds complexity and cost to their IT infrastructure.

But, in reality, multi-factor authentication doesn’t add much overhead.

Instead, it provides additional layers of protection against cyberattacks.

3. Complexity

Organizations sometimes find it difficult to integrate multi-factor authentication into their existing systems.

For example, they might have to replace old software or change user interfaces.

Some Potential Solution Ideas

If you’re struggling to implement multi-factor authentication, here are some tips to help you overcome these challenges.

1. Educate Employees About Multi-Factor Authentication

Educating employees about multi-factor authentication helps them understand its importance.

Make sure employees know that using multi-factor authentication reduces the likelihood of fraud and improves overall security.

2. Use Technology That Works For You

Multi-factor authentication tools are becoming more popular by the day. Many low-cost, or even free, solutions exist from vendors like Microsoft, DUOand others.

Look for solutions that have easy integration with your existing business infrastructure and systems.

3. Work With A Partner

A partner who has experience implementing multi-factor authentication can be helpful.

An experienced partner can provide guidance and support throughout the implementation process.

4. Make Sure The Solution Is Right For You

Before choosing a solution, make sure it meets your organization’s needs.

SSL Certificate High-Level Best Practices

Posted on November 8, 2021 by Brent Huston

SSL certificates are an essential part of online security. They protect websites against hackers who try to steal information such as credit card numbers and passwords. In addition, they ensure that customers trust the site and its content.

Almost 50% of the top one million websites use HTTPS by default (they redirect inquiries of HTTP pages to URLs with HTTPS). (comodosslstore.com)As such, even pages that don’t deal with confidential data are being deployed using SSL. The underlying certificates to power the encryption are available from a variety of commercial providers, and even the pro-bono resource https://letsencrypt.org. No matter where you get your certificate from, here are a few resources for high-level best practices.

Trust Your Certificate Provider

Since certificates provide the basis for the cryptography for your site, their source is important. You can find a trustworthy list of providers for certificates here. https://www.techradar.com/news/best-ssl-certificate-provider. Beware of commercial providers not found on this list, as some of them may be sketchy at best, or dangerous at worst. Remember, the Let’s Encrypt project above is also highly trusted, even though they are not a commercial firm.

Manage Versions and Algorithms

Make sure you disable SSL and TLS 1.0 on the server. That version has known vulnerabilities. If possible, and there are no impacts on your users, consider removing 1.1 and 1.2 as well. 1.3 fixes a lot of the known issues with the protocol and supports only the known secure algorithms.

In cryptography, cipher suites play an important part in securing connections by enabling encryption at different levels. You shouldn’t be using an old version of a cryptographic protocol if there’s a newer one available; otherwise, you may put your site’s security at risk. Using secure cipher suites that support 128-bit (or more) encryption is crucial for securing sensitive client communications.

Diffie Hellman Key Exchange has been shown to be vulnerable when used for weaker keys; however, there is no known attack against stronger keys such as 2048-bits. Make sure you use the strongest settings possible for your server.

Manage and Maintain Certificate Expiration

As of Sept. 1, 2020, Apple’s Safari browser will no longer trust certificates with validity periods longer than 398 days, and other browsers are likely to follow suit. Reducing validity periods reduces the time period in which compromised or bogus certificates can be exploited. As such, any certificates using retired encryption algorithms or protocols will need to be replaced sooner. (searchsecurity.techtarget.com)

Maintain a spreadsheet or database of your certificate expiration dates for each relevant site. Make sure to check it frequently for expiring certificates to avoid user issues and browser error messages. Even better is to use an application or certificate management platform that alerts you in plenty of time to upcoming certificate expirations – thus, you can plan accordingly. Best of all, if possible, embrace tools and frameworks for automating certificate management and rotation – that makes sure that you are less likely to have expiration issues. Most popular web frameworks now have tools and plugins available to perform this for you.

Protect Your Certificates and Private Keys

Remember that your certificate is not only a basis for cryptography, but is also a source of identification and reputation. As such, you need to make sure that all certificates are stored properly, securely and in trusted locations. Make sure that web users can’t access the private certificate files, and that you have adequate back up and restore processes in place.

Make sure that you also protect the private keys used in certificate generation. Generate them offline, if possible, protect them with strong passwords and store them in a secure location. Generate a new private key for each certificate and each renewal cycle.

Revoke your certificate or keys as quickly as possible if you believe they have been compromised.

Following these best practices will go a long way to making your SSL certificate processes safer and more effective. Doing so protects your users, your reputation and your web sites. Make sure you check back with your certificate provider often, and follow any additional practices they suggest.

The Need for an Incident Recovery Policy (IRP)

Posted on February 2, 2015 by Brent Huston

Organizations have been preparing for information security issues for a number of years now and many, if not most, have embraced the need for an incident response policy and process. However, given the recent spate of breaches and compromises that we have analyzed and been involved in over the last year, we have seen an emerging need for organizations to now embrace a new kind of policy – a security incident RECOVERY policy.

This policy should extend from the incident response policy and create a decision framework, methodology and taxonomy for managing the aftermath of a security incident. Once the proverbial “fire has been put out”, how do we clean up the mess, recreate the records we lost, return to business as usual and analyze the impacts all of this had on our operations and long term bottom line? As a part of this process, we need to identify what was stolen, who the likely benefactors are, what conversion events have taken place or may occur in the future, how the losses impact our R&D, operational state, market position, etc. We also need to establish a good working model for communicating the fallout, identified issues, mitigations, insurance claims, discoveries and lessons learned to stakeholders, management, customers, business partners and shareholders – in addition to the insurance companies, regulators and law enforcement.

As you can imagine, this can be a very resource intensive process and since post-incident pressues are likely to remain high, stress levels can be approaching critical mass and politics can be rampant, having a decision framework and pre-developed methodology to work from can be a life saver. We suggest following the same policy development process, update timeframes and review/practice schedules as you do for your incident response policy.

If your organization would like assistance developing such a policy, or would like to work through a training exercise/practice session with an experienced team, please feel free to work with your account executive to schedule such an engagement. We also have policy templates, work sheets and other materials available to help with best practice-based approaches and policy creation/reviews.

Network Segmentation: A Best Practice We Should All be Using

Posted on January 16, 2015 by Brent Huston

It would be nice to be able to say that we are winning the war; that network security efforts are slowly getting the better of the bad guys. But I can’t do that. Despite all the money being thrown at security tools and hosted services, the cyber-thugs are improving their game at a faster rate than we are. The ten worst known cyber security breaches of this century have all taken place since 2008, and 2013 and 2014 are notorious for their information security incidents.

I think there are a multitude of reasons for this state of affairs to exist. One is confusion, indecisiveness and slow reaction times among regulatory bodies and standards providers. Another is the “check the box” compliance mentality that exists both in government agencies and in the private sector. A third is simply the insane rate of innovation in the information technology realm. There are many more. But despite the reasons, one thing is clear: we have to stop rigidly complying with baseline standards and move into the more flexible and effective world of best practices. And today the best practice I want to touch on is network segmentation.

In our business we see a lot of computer networks that are just “flat”. There is little or no network segmentation and anyone on the inside can pretty much see everything. I can’t begin to tell you how easy this kind of setup makes it for us during penetration testing – success is virtually assured! And it’s amazing how even just basic network segmentation can slow us down or stop us all together.

A good reason to start with network segmentation is that you can go at in easy stages. Maybe you can begin by segmenting off a separate development or test network. Those are pretty basic and can give your networking team some valuable experience for more difficult efforts to come. Then you can ensure that “user space” is separated from “server space”. Doing just that much can have an amazing effect – it really helps to thwart successful cyber-attacks.

As the team gains confidence in their abilities, they can move onto the next step: real enclaving of the network. This is anything but a trivial effort, and it requires detailed knowledge of the various functions of the different business departments and how information moves into and out of each one of them (a task made very much easier if the company has a good business continuity program and business impact analysis in place). But in the long run these efforts will be well worth the trouble. It is very difficult indeed to gain access to or exfiltrate information from a well enclaved network – especially from the Internet.
