What is a vCISO?

A vCISO, virtual CISO, or virtual Chief Information Security Officer is a highly qualified cybersecurity expert who provides IT security and compliance services on a contractual basis. Unlike a full-time CISO, a vCISO works remotely and collaborates with an organization’s executive team to protect against security threats and ensure compliance with industry regulations.

As a cybersecurity expert, a vCISO brings years of experience and a wide range of skills. They deeply understand security practices, threat landscapes, and industry standards. With this knowledge, they can assess an organization’s security posture, identify potential gaps and risks, and develop a comprehensive cybersecurity strategy.

A vCISO’s role is to provide unbiased advice and guidance to the organization’s leadership team. They work closely with the executive team to align security objectives with business goals. VCISOs can help establish and implement security policies, compliance standards, and best practices by leveraging their technical expertise and industry knowledge.

By hiring a vCISO on a contractual basis, organizations gain access to a team of experts without the commitment of a full-time hire. This flexible and cost-effective approach allows businesses to benefit from the expertise of a seasoned professional while optimizing their security program. Ultimately, a vCISO helps organizations enhance their security posture and proactively mitigate cyber threats.

What does a virtual Chief Information Security Officer do?

A virtual Chief Information Security Officer (vCISO) plays a critical role in assisting organizations in developing and managing their information security program. One of the primary responsibilities of a vCISO is to create and implement a comprehensive security strategy for the organization. This includes identifying and prioritizing security threats, developing security policies and procedures, and establishing security controls to mitigate risks.

In addition to creating the security strategy, a vCISO coordinates and manages security audits conducted within the organization. They work closely with internal and external auditors to ensure the organization’s security practices and controls meet regulatory requirements and industry standards. This involves conducting risk assessments, reviewing security controls, and implementing necessary changes to enhance the organization’s security posture.

Furthermore, a vCISO evaluates third-party vendors and assesses their security capabilities. They ensure that third parties comply with the organization’s security requirements and implement necessary security measures to protect its data and systems from potential risks.

A crucial part of a vCISO’s role is presenting the organization’s security posture to stakeholders, such as the executive team and board members. They regularly update the organization’s security posture, including identified vulnerabilities or emerging threats. This helps stakeholders make informed decisions regarding the organization’s security investments and priorities.

A vCISO plays a vital role in helping organizations build a robust and effective information security program by fulfilling these responsibilities. They bring their expertise to develop a comprehensive security strategy, coordinate audits, evaluate third parties, and present the organization’s security posture to stakeholders.

As organizations continue to move their operations to cloud services, it is becoming increasingly important for information security and risk management teams to understand how they can support financial operations (FinOps). FinOps is a management practice that promotes shared responsibility for an organization’s cloud computing infrastructure and cloud cost management. In this post, we will explore some ways in which the information security and risk management team can support FinOps initiatives.

1. Establishing Governance: Information security and risk management teams can play a vital role in helping FinOps teams establish effective governance. This includes creating a framework for budget management, setting up policies and procedures for cloud resource usage, and ensuring that all cloud infrastructure is secure and meets compliance requirements.

2. Security Awareness Training: Information security and risk management teams can provide security awareness training to ensure that all cloud practitioners are aware of the importance of secure cloud computing practices. This includes data protection, authentication protocols, encryption standards, and other security measures.

3. Cloud Rate Optimization: Information security and risk management teams can help FinOps teams identify areas of cost optimization. This includes analyzing cloud usage data to identify opportunities for cost savings, recommending risk-based ways to optimize server utilization, and helping determine the most appropriate pricing model for specific services or applications.

4. Sharing Incident Response, Disaster Recovery, and Business Continuity Insights: Information security and risk management teams can help FinOps teams respond to cloud environment incidents quickly and effectively by providing technical support in the event of a breach or outage. This includes helping to diagnose the issue, developing mitigations or workarounds, and providing guidance on how to prevent similar incidents in the future. The data from the DR/BC plans are also highly relevant to the FinOps team mission and can be used as a roadmap for asset prioritization, process relationships, and data flows.

5. Compliance Management: Information security and risk management teams can help FinOps teams stay compliant with relevant regulations by managing audits and reporting requirements, ensuring that all relevant security controls are in place, auditing existing procedures, developing policies for data protection, and providing guidance on how to ensure compliance with applicable laws.

The bottom line is this: By leveraging the shared data and experience of the risk management and information security teams, FinOps teams can ensure their operations are secure, efficient, and completely aligned with the organization’s overall risk and security posture. This adds value to the work of all three teams in the triad. By working together, the teams can significantly enhance the maturity around technology business management functions. All-in-all, by working together, the teams can create significantly better business outcomes.

How To Handle Leaked Credentials

Posted on by
Reply

OK, so you used ClawBack™ or some other tool and found leaked credentials linked to one of your employees on the web. Now, what do you do?

First, don’t panic. Leaked credentials happen all of the time. On average, it was discovered that employee email credentials from 10% of all Fortune 500 companies have been leaked in some form of data breach. (blog.finjan.com)  Another report published recently suggests that the web currently hosts leaked credentials of employees for 97% of the top 1,000 global companies – many stemming from third-party data breaches. (blog.finjan.com)

Once you come to terms with your find, it’s time to get down to business researching the issue. The first step is to determine what kind of data you have identified. Usually, leaked credentials come with a user ID like an email, system login name, or the like. Presumably, this is how you found the credentials in the first place. Next, determine if you have a password and/or hash for that user that was contained in the leak. If you found only a list of emails or names, there is not much actionable intelligence there, beyond maybe letting those users know that they are at increased risk for phishing and reminding them to be vigilant.

If, however, you have a password or hash tied to one of your user names in the leak, a few more steps are involved. If you have a password, the first step is to determine if that password meets whatever password policies you have defined across the organization. This is a key leverage point for identifying potential leaks – many, if not most, leaked passwords come from third-party systems and websites that are compromised by attackers but are only used by the firm’s employees. It’s pervasive for industry sites, or shopping sites to be linked to your employee’s identity – it could be as simple as your employee signed up for the site with their work email, and that site got breached. If that is the case, then as long as your employee doesn’t use that password at work (or similar passwords: eg: Summer12 and Summer13, etc.) there is little risk to the firm. If the password would not meet your password policy for your domain, webmail, and other applications, then this is likely the case. If that happens, simply contact the employee, advise them of the leaked credential, and make sure that they understand to change their passwords anywhere they used that password in their online life.

But, what if the password could be one of your domain or webmail accounts? If the password would meet your policies, then immediately force a password change on all systems for that user. If possible, you should also terminate any open sessions and force the user to change their credentials. While a determined attacker may exploit this process to reset the password themselves if they have the ability, it prevents any non-resourced attackers from exploiting the credentials. The worst case is that an employee loses a current session and has to reset their passwords to continue working.

However, don’t stop there – contact the user and advise them of the leaked credential. Ask them if it was used on any work-related systems or applications, and if so, immediately begin an investigation on those systems looking for signs of illicit access. This should be performed using intensive log reviews and should go back to the date of the user’s previous password change whenever possible. Do not depend on the leak date, if shown, as the boundary for the incident. Attackers may have had knowledge and access prior to making the leak public. Often, attackers use compromised accounts for some time, getting what they want from the victim, and then release the stolen credentials to other attackers via a sale, or to the public, in the hopes that the additional attacker traffic will hide the original compromise.

Lastly, if you only have a hash of a potential password, I would still follow the process above. Most hashes can be broken given enough resources. Thus, it is erring on the side of caution to follow the above process, and accept the hash as a credential that could be in use in your environment.

Got other workarounds for leaked credentials? I’d love to hear them. Drop me a line on Twitter, and let me know (@lbhuston). I’ll share any insights in future posts.

Automating SSL Certificate Management with Certbot and Let’s Encrypt

Posted on by
Reply
As we posted previously, following best practices for SSL certificate management is critical to properly secure your site. In that post, we discussed automating certificate management as a best practice. This post is an example of how to do just that.
 
To do so, we will use the highly-trusted free certificate provider Let’s Encrypt. We will also leverage the free certificate automation tool Certbot.
 

Installing Certbot

Installing Certbot is pretty easy, overall, but you do need to be comfortable with the command line and generally know how to configure your chosen web server. That said, if you check out the Certbot site, you will find a dropdown menu that will let you pick your chosen web server and operating system. Once you make your selections, simply follow the on-screen step-by-step instructions. In our testing, we found them to be complete and intuitive.
 

That’s It!

Following the on-screen instructions will have:

  • Certbot installed
  • Configure your web server for the certificate
  • Generate, get and install the certificate
  • Implement automatic renewals of the certificate to prevent expiration

You can literally go from a basic website to fully implemented and automated SSL in a matter of moments. Plenty of support is available from EFF for Certbot, or via Let’s Encrypt. In our testing, we ran into no issues and the implementation completed successfully each time.

Give it a shot! This might be one of the easiest and most effective security controls to automate. Together, Certbot and Let’s Encrypt can create a no-cost cryptography solution for your web sites in a very short amount of time.

Last Quick and Dirty Log Tip for the Week

Posted on by
Reply

OK, so this week I posted two other blog posts about doing quick and dirty log analysis and some of the techniques I use. This one also covers converting column logs to CSV.

After the great response, I wanted to drop one last tip for the week. 

Several folks asked me about re-sorting and processing the column-based data in different ways and to achieve different analytical views. 

Let me re-introduce you to my friend and yours, sort.

In this case, instead of using the sort -n -r like before (numeric sort, reverse order), we can use:

  • sort -k# -n input_file (where # is the number of the column you’d like to sort by and the input file is the name of the file to sort)
    • You can use this inline by leveraging the pipe (|) again – i.e.: cat input.txt | sort -k3 -n (this types the input file and sends it to sort for sorting on the third column in numeric order) (-r would of course, reverse it…)
    • You can write the output of this to a file with redirects “> filename.txt”, i.e.: cat input.txt | sort -k3 -n -r > output.txt
      • You could also use “>>” as the redirect in order to create a file if it doesn’t exist OR append to a file if it does exist… i.e..:  cat input.txt | sort -k3 -n -r >> appended_output.txt

That’s it! It’s been a fun week sharing some simple command line processing tips for log files. Drop me a line on Twitter (@lbhuston) and let me know what you used them for, or which ones are your favorite. As always, thanks and have a great weekend! 

Quick And Dirty Log Analysis Followup

Posted on by

Earlier this week, I posted some tips for doing Quick and Dirty PA Firewall Log Analysis.

After I posted this, I got a very common question, and I wanted to answer it here.

The question is something along the lines of “When I use the techniques from your post, the outputs of the commands are column separated data. I need them to be CSV to use with my (tool/SEIM/Aunt Gracie/whatever). How can I convert them?” Sound familiar?

OK, so how do we accomplish this feat of at the command line without all of the workarounds that people posted, and without EVER loading Excel? Thankfully we can use awk again for this.

We can use:

  • awk ‘BEGIN { OFS = “,”} ; {print $1,$2,$3}’
    • Basically, take an input of column data, and print out the columns we want (can be any, in this case I want the first 3 columns), and make the outputs comma delimited.
    • We can just append this to our other command stacks with another pipe (|) to get our output CSV
  • Example: cat log.csv | awk ‘BEGIN { FS = “,”} ; {print $8,$9}’ | sort -n | uniq -c | sort -n -r | awk ‘BEGIN { OFS = “,”} ; {print $1,$2,$3}’
    • In this example, the source IP and destination IP will be analyzed, and the reduced to unique pairs, along with the number of times that that pair is duplicated in the input log (I use this as a “hit rate” as I described earlier
      • A common question, why do I ask for two columns in the first awk and then ask for three columns in the second awk?
        • The answer of course, is that the first awk prints the unique pairs, but it also adds a column of the “hit rate”, so to get the output appropriately, I need all three fields.

So, once again, get to know awk. It is your friend.:)

PS – Yes, I know, there are hundreds of other ways to get this same data, in the same format, using other command line text processing tools. Many may even be less redundant than the commands above. BUT, this is how I did it. I think it makes it easy for people to get started and play with the data. Post your ways to Twitter or share with the community. Exploration is awesome, so it will encourage users to play more. Cool! Hit me on Twitter if you wanna share some or talk more about this approach (@lbhuston).
