Can a NOC Provide SOC Functionality?
A typical Network Operations Center will use tools such as intrusion detection systems, firewalls, packet sniffers, log analyzers, vulnerability scanners, etc., but these tools alone won’t cut it when it comes to providing an effective SOC function. The NOC needs to understand how all those tools work together so that it can properly identify potential problems before they become serious ones.
The NOC also has to know what constitutes a threat or attack on its own networks, which means having some understanding of networking fundamentals. This includes knowing about IP addressing schemes, TCP/IP protocols, routing concepts, VPN technologies, wireless LAN standards, WAN connectivity options, and more. It’s important to note here that this knowledge doesn’t necessarily mean you’ll be able to design your own solutions; rather, it simply means you’re aware enough to recognize if something isn’t working correctly.
The NOC should also be familiar with common attacks against computer networks, including denial-of-service attacks, distributed DoS, buffer overflows, viruses, worms, Trojan horses, spyware, adware, rootkits, and other malicious software.
How Does a NOC Perform Incident Response?
An incident response plan defines procedures for responding to incidents within a company. An IRP typically covers everything from identifying the problem to restoring normal operations after the issue has been resolved. A well-written IRP ensures that every aspect of the process is covered, from initial notification through resolution. In fact, many companies require their employees to follow specific steps during any type of emergency situation.
An IRP may include:
- Notifying appropriate personnel
- Identifying affected areas
- Documenting events
- Assigning responsibilities
- Establishing contact points
- Developing recovery plans
- Providing training
- Reporting results
What Kind of Documentation Should I Keep?
Documentation is critical to maintaining good records of past activities and future planning. Keep track of all changes made to existing documents and new documents created. You don’t want to lose anything! Also make sure to document all actions taken during an investigation. If there was no action taken, then why did nothing happen? Make notes regarding each step along the way. These details help ensure proper accountability and prevent mistakes down the road.
Documentation requirements vary depending upon industry regulations, internal policies, and individual business practices. Some organizations even create speial forms just for documenting certain types of information.
For example, financial institutions often maintain detailed logs of transactions performed using automated teller machines. They record transaction data such as time, date, amount, user ID, PIN number, location, and machine serial numbers. Other industries might require similar documentation. For instance, medical facilities usually keep extensive patient histories, while law enforcement agencies collect evidence at crime scenes.
Regardless of how much detail you choose to capture, always remember to store these records safely so that they remain available when needed. The best place to archive log files is offsite, preferably in a secure facility where authorized individuals will only access.
Why is My Organization Vulnerable?
Vulnerability assessment tools provide valuable insight into potential risks facing an organization. Vulnerabilities aren’t limited to physical systems like computers and servers.
A vulnerability exists whenever someone or something could potentially cause harm if exploited. This includes people, processes, applications, hardware devices, operating system vulnerabilities, etc.
Some examples of possible vulnerabilities include:
- Unpatched Windows operating systems running Internet browsers
- Weak passwords on websites
- Poorly configured firewalls
- Lack of antivirus protection
- Incorrect use of encryption technology
- Misconfigured email services
- Outdated server configurations
In conclusion, the most important thing to consider before implementing a comprehensive cybersecurity program is whether your current infrastructure supports what’s required. It’s also crucial to understand which components of your environment pose the greatest risk. Once this knowledge base is established, you’ll know exactly what needs to change.
The next step is to develop a strategy designed specifically for your organization. As with other aspects of IT management, developing a solid approach requires careful consideration of costs versus benefits. Finally, implement the solution according to your chosen methodology.
