The Human Factor: Enhancing Security Awareness Training Effectiveness

Posted on November 9, 2023 by John Davis

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.

What to Look For in a DHCP Log Security Audit

Posted on November 1, 2023 by Brent Huston

Examining the DHCP logs

In today’s ever-evolving technology landscape, information security professionals face numerous challenges in ensuring the integrity and security of network infrastructures. As servers and devices communicate within networks, one crucial element to consider is DHCP (Dynamic Host Configuration Protocol) logs. These logs provide valuable insights into network activity, aiding in identifying security issues and potential threats. Examining DHCP logs through a thorough security audit is a critical step that can help organizations pinpoint vulnerabilities and effectively mitigate risks.

Why are DHCP Logs Important?

DHCP servers are central in assigning IP addresses and managing network resources. By constantly logging activities, DHCP servers enable administrators to track device connections, detect unauthorized access attempts, and identify abnormal network behavior. Consequently, DHCP logs clarify network utilization, application performance, and potential security incidents, making them a vital resource for information security professionals.

What Security Issues Can Be Identified in DHCP Logs?

When analyzing DHCP logs, security professionals should look for several key indicators of potential security concerns. These may include IP address conflicts, unauthorized IP address allocations, rogue DHCP servers, and abnormal DHCP server configurations. Additionally, DHCP logs can help uncover DoS (Denial of Service) attacks, attempts to bypass network access controls, and instances of network reconnaissance in some circumstances.

In conclusion, conducting a comprehensive security audit of DHCP logs is an essential practice for information security professionals. By leveraging the data contained within these logs, organizations can identify and respond to potential threats, ensuring the overall security and stability of their network infrastructure. Stay tuned for our upcoming blog posts, where we will delve deeper into the crucial aspects of DHCP log analysis and its role in fortifying network defenses.

Parsing the List of Events Logged

When conducting a DHCP log security audit, information security professionals must effectively parse the list of events logged to extract valuable insights and identify potential security issues.

To parse the logs and turn them into easily examined data, obtain the log files from the DHCP server. These log files are typically stored in a default logging path specified in the server parameters. Once acquired, the logs can be examined using various tools, including the server management console or event log viewer.

Begin by analyzing the log entries for critical events such as IP address conflicts, unauthorized IP address allocations, and abnormal DHCP server configurations. Look for any indications of rogue DHCP servers, as they can pose a significant security risk.

Furthermore, pay close attention to entries related to network reconnaissance, attempts to bypass network access controls and DoS attacks. These events can potentially reveal targeted attacks or malicious activities within the network.

By effectively parsing the list of events logged, information security professionals can uncover potential security issues, identify malicious activities, and take necessary measures to mitigate risks and protect the network infrastructure. It is crucial to remain vigilant and regularly conduct DHCP log audits to ensure the ongoing security of the network.

Heuristics that Represent Malicious Behaviors

When conducting a DHCP log security audit, information security professionals should look for specific heuristics representing potentially malicious behaviors. 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.

Some Thoughts on Security Policy Violation and Terminations

Posted on September 26, 2023 by Brent Huston

There was recently a discussion on one of my forums that I visited about whether or not employees should be terminated if they violate information security policies.

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.

What do you think about termination for security policy violations? What have you seen that works, and what doesn’t in your experience? Drop me a line on Twitter (@lbhuston) or Mastodon (@lbhuston@mastodon.social) and let me know your opinion.
