A Plea for Multi-Factor Authentication

Posted on by

Despite all our network security efforts, attackers continue to compromise our private data and systems at an alarming rate. What’s worse, they do this using the same chain of steps. They find some way to get access to the internal network, they find a way to navigate around the network, they elevate their privileges and, voila! They can toy with your data and systems to the level of their expertise and rapaciousness.

The thing is, if we can break any one of these steps, we can most often keep the attackers from reaching their goals. And one of the most useful and available tools out there to help organizations disrupt the chain is multi-factor authentication (MFA). MFA can be very effective in preventing initial access to the network, it can also be very effective in preventing elevation of privileges and, therefore, can help prevent attackers navigating around the network. Because of this, we at MicroSolved plead with all of our customers and readers to employ MFA to the fullest possible extent.

Certainly, users should be required to employ MFA when accessing the network remotely. This is necessary to prevent attackers who have accessed users’ credentials from getting that initial foothold on the network. I personally advocate using MFA for any network or AD access.

The Center for Internet Security (CIS) V8 Security Controls also require employing MFA for all externally-exposed enterprise or third-party applications wherever supported. They also state that enforcing MFA for this purpose can be accomplished safely through the use of a directory service or SSO provider.

CIS V8 controls also require the use of MFA for administrative access. This also needs to be accompanied by requiring that all network administration be accomplished using dedicated administrator accounts. Administrators should use separate access accounts for all other network activities. These controls help tremendously in preventing attackers from elevating their privileges by simply gaining access to a normal user account.

In these dangerous times, all organizations should at least employ MFA as described above. When combined with encryption of sensitive data across your network and backups, these controls pose a formidable obstacle for attackers to overcome.

The Human Factor: Enhancing Security Awareness Training Effectiveness

Posted on by

Over the last 15 years or so, we have greatly improved network security. We started by beefing up network perimeter security, and then moved on to improve internal network security and resistance to malware. So why are the number of network infiltrations and data breaches greater and more damaging than ever? I think the main reason is because cyber-attackers are employing alternate techniques such as phishing attacks to gain their primary entry to networks. And unfortunately, susceptibility to phishing attacks is primarily a human problem, not a technological one.

So, what can we do to fight such an insidious threat? We can make sure that we are doing all we can to turn personnel from our number one security risk into our number one security asset. And to do that, we not only need to make everyone in the organization aware of modern attack techniques, we also need to enlist their aid in detecting and reporting suspected cyber-incidents. Why not employ real, human intelligence to the problem rather than artificial intelligence?

The first stage in this process is to ensure that all your personnel receive comprehensive security awareness training and continuous security reminders. Personnel need training to understand how networks are compromised and what common network attacks look like. They also need to know how to react to suspected security attacks, and who and how to report these issues to. In addition, you need to make sure that your help desk, IT and security personnel are open to these questions and reports and do not look on them as a pain. You should also ensure that your personnel receive continuous updates on the latest attacks and techniques being employed by attackers.

To get your personnel to become security assets, it helps to be innovative in your approach to information security and awareness training. Right now, you are probably employing web-based security training modules to make your personnel aware of security issues, and there is nothing wrong with that. However, going through these modules is not usually viewed as a fun time by most personnel, and retention and buy-in is going to suffer. So why not supplement or replace part of this online training with group security training and/or awareness meetings? For example, you could have quarterly security lunches where your personnel not only receive up-to-date security information, but are provided with a good meal in the bargain. People always react well to events where food is involved!

Another technique that could be used to get personnel on your side in this effort is to provide them with incentives for good security performance. You could reward personnel for catching and reporting security events or for coming up with good suggestions for improving security in your organization. These incentives do not have to be costly either. People react just as well to public praise as they do to monetary incentives. There’s nothing like a good pat on the back! Put their pictures up on the bulletin board or on the website. Other incentives could be a special parking place they get to use for a week, or an afternoon off with pay; anything that might make other employees want to do well and get the same rewards.

Once you have put a good security training and awareness program in place, you need to have techniques in place for judging its effectiveness. One way to do this is to test personnel on their retention of the security issues they have been taught. I personally recommend not performing these tests immediately after the training session. I would quiz personnel on the information after a day or two had passed. This will help you determine how much long-term retention you are liable to get. In addition, you could perform security tests on your personnel, such as phishing tests. You could send personnel suspicious emails messages or could text or call them with suspicious requests. You should track how personnel do on these tests as well. This will help you identify persons that are more susceptible to cyber-attacks and give you the opportunity to provide them with extra training or incentives as needed. Whatever you come up with, remember that in this environment security and awareness training are at least as important as any other security measures you are employing to protect your private systems and information.

These heuristics can help identify security issues and prevent potential threats. It’s essential to understand what these heuristics mean and how to investigate them further.

Some examples of potentially malicious DHCP log events include:

1. Multiple DHCP Server Responses: This occurs when multiple devices on the network respond to DHCP requests, indicating the presence of rogue DHCP servers. Investigate the IP addresses associated with these responses to identify the unauthorized server and mitigate the security risk.

2. IP Address Pool Exhaustion: This event indicates that all available IP addresses in a subnet have been allocated or exhausted. It could suggest an unauthorized device or an unexpected influx of devices on the network. Investigate the cause and take appropriate actions to address the issue.

3. Unusual DHCP Lease Durations: DHCP lease durations outside the normal range can be suspicious. Short lease durations may indicate an attacker attempting to maintain control over an IP address. Long lease durations could suggest an attempt to evade IP address tracking. Investigate these events to identify any potential malicious activities.

Summary

A DHCP log security audit is crucial for information security professionals to detect and mitigate potential threats within their network. By analyzing DHCP log events, security teams can uncover malicious activities and take appropriate actions to protect their systems.

In this audit, several DHCP log events should be closely examined. One such event is multiple DHCP server responses, indicating the presence of rogue DHCP servers. Investigating the IP addresses associated with these responses can help identify unauthorized servers and address the security risk.

Another event that requires attention is IP address pool exhaustion. This event suggests the allocation of all available IP addresses in a subnet or an unexpected increase in devices on the network. Identifying the cause of this occurrence is vital to mitigate any potential security threats.

Unusual DHCP lease durations are also worth investigating. Short lease durations may suggest an attacker’s attempt to maintain control over an IP address, while long lease durations could indicate an effort to evade IP address tracking.

By conducting a thorough DHCP log security audit, security teams can proactively protect their networks from unauthorized devices, rogue servers, and potential malicious activities. Monitoring and analyzing DHCP log events should be an essential part of any organization’s overall security strategy.

The discussion was heated by some parties, and the threads grew long and multi-layered. 

I asked Frase.io to summarize that discussion and pull together a relevant set of ideas stemming from it. Here is what the AI tool created:

– Following information security policies is crucial for the protection of sensitive data and the overall cybersecurity of a company. Therefore, it is important to discuss whether employees should face consequences for not adhering to these policies.
– When employees fail to follow information security policies, it can put the entire organization at risk. The consequences of a data breach can be severe, including financial loss, damage to reputation, and legal implications. Therefore, some argue that firing employees who do not comply with these policies is necessary to maintain a secure work environment.
– On the other hand, it is essential to consider the context and severity of the violation before deciding on termination. Employees may unintentionally make mistakes or be unaware of the policies, in which case education and training may be more appropriate than immediate termination.
– Implementing a fair and consistent approach to enforcing information security policies is crucial. This includes clear communication of expectations, regular training programs, and providing employees with the necessary tools and resources to comply with policies.
– Ultimately, the decision to fire an employee for not following information security policies should be based on a thorough assessment of the situation. It is important to balance the need for security with fairness and understanding, considering the employee’s intentions, previous behavior, and potential for improvement.

After all of the rhetoric and the flames, this seems to be a rational approach to me. I think that stripped of the emotions of the participating infosec practitioners; there is logic here that is useful.

Fall is in the air, and along with pumpkin spice lattes and cozy sweaters, it’s also the perfect time for information security teams to step out of their digital shells and engage with other departments in their organizations. While security is serious business, there’s no harm in adding a dash of fun to foster better collaboration and understanding. Here are five light-hearted yet factual activities to spice up your information security team’s fall:

1. Cybersecurity Pumpkin Carving Contest

Unleash your inner artist and host a cybersecurity-themed pumpkin carving contest. Encourage teams from all departments to carve out their favorite security tools, icons, or even infamous cyber villains. Not only does this activity tap into everyone’s creative side, but it also sparks conversations about the importance of protecting the digital realm while having a gourd time!

2. “Escape the Phishing” Maze

Turn the concept of an escape room into an interactive cybersecurity challenge. Create a “phishing” maze where participants need to navigate through a series of puzzles and scenarios related to online security. This activity not only educates participants about the dangers of phishing attacks but also gets them working together to solve problems, fostering team spirit.

3. Crypto Treasure Hunt

Transform your office space into a treasure hunting ground by organizing a crypto-themed treasure hunt. Provide clues related to encryption, decryption, and security best practices that lead teams from one clue to another. Not only does this activity promote learning about cryptography, but it also encourages friendly competition among departments.

4. Security Awareness Fair

Set up a “Security Awareness Fair” in your office’s common area. Each department can have its own booth showcasing their approach to security. From IT’s “Spot the Vulnerability” game to HR’s “Password Strength Analyzer,” everyone gets to display their security prowess in a fun and informative way. This fair promotes cross-departmental engagement and ensures that everyone learns a thing or two about cybersecurity.

5. Cyber Movie Night

Host a cybersecurity-themed movie night with popcorn and cozy blankets. Screen movies like “Hackers,” “WarGames,” or even cybersecurity documentaries. After the movie, encourage lively discussions about what’s accurate and what’s exaggerated in the portrayal of hacking and security. It’s a laid-back way to bridge the gap between tech-savvy and non-technical teams.

Remember, the goal of these activities isn’t just to have fun, but to build bridges between information security teams and other departments. By approaching cybersecurity engagement with a light-hearted touch, you’re more likely to break down barriers, share knowledge, and create a culture of collaboration that lasts beyond the fall season. So, gear up for a season of learning, laughter, and interdepartmental camaraderie!
