Cybersecurity Theatre: Effective Strategies For SecOps Teams

In the realm of cybersecurity, many SecOps teams often find themselves bogged down by activities that yield limited returns on investment (ROI). The core mission of SecOps is to ensure that major incidents are prevented and that medium to low-level events are managed efficiently. However, the reality is that a significant portion of resources is wasted on tasks that do not contribute meaningfully to this mission.

Key Areas of Waste in SecOps:

1. Phishing Simulations:

While phishing simulations are a common practice, they often fail to address the root cause of the problem. A small percentage of users will always fall for phishing attempts, and instead of repeatedly testing them, SecOps should focus on identifying these individuals and implementing compensating controls to limit the impact of their actions. Automation can reduce the time spent on this activity to just 2-3 hours per month, freeing up resources for more critical tasks.

2. Vulnerability Management:

Vulnerability management is another area where resources are often misallocated. Instead of trying to patch every vulnerability, teams should prioritize based on the availability of public exploits and whether the infrastructure is publicly exposed. The key is to foster an engineering culture that prioritizes timely patching, rather than relying on expensive tools that promise to solve the problem.

3. Tool Sprawl:

The tendency to adopt multiple security tools without proper integration or management leads to tool sprawl. This not only increases complexity but also drains the SecOps budget. Instead of jumping on every new tool, teams should focus on fully deploying and managing the tools they already have.

4. Tabletop Exercises (TTX):

While tabletop exercises can be beneficial for less mature organizations, their ROI diminishes quickly. For more advanced teams, live command-line exercises with red and purple teams are far more effective in preparing for real-world incidents.

Effective Solutions:

The most effective approach to cybersecurity remains a combination of People, Process, and Technology, in that order. AI and cloud solutions, while useful, are not silver bullets and can introduce additional attack surfaces if not managed properly.

You Should Know: Practical Commands and Codes

Linux Commands for SecOps:

Network Scanning with Nmap:
```
nmap -sV -O target_ip
```
This command scans a target IP for open ports, services, and operating system details.
Log Analysis with Grep:
```
grep "Failed password" /var/log/auth.log
```
This command filters out failed login attempts from the authentication log, useful for identifying brute force attacks.
File Integrity Checking with AIDE:
```
aide --check
```
AIDE (Advanced Intrusion Detection Environment) checks the integrity of files and directories, alerting you to any unauthorized changes.

Windows Commands for SecOps:

Check Open Ports with Netstat:
```
netstat -an | find "LISTENING"
```
This command lists all listening ports on a Windows machine, helping you identify potential unauthorized services.
Audit Logs with PowerShell:
```
Get-EventLog -LogName Security -Newest 50
```
This PowerShell command retrieves the 50 most recent entries from the Security log, useful for auditing purposes.
Patch Management with WMIC:
```
wmic qfe list brief
```
This command lists all installed updates, helping you ensure that your system is up-to-date with the latest patches.

What Undercode Say:

Cybersecurity is not just about deploying tools; it’s about creating a culture of security within the organization. By focusing on the right priorities—people, processes, and then technology—SecOps teams can significantly reduce their attack surface and improve their overall security posture. Automation, proper patch management, and effective use of resources are key to achieving this goal. Remember, the goal is not to eliminate all risks but to manage them in a way that aligns with the organization’s risk appetite and business objectives.
