search patterns for monitoring cyber attacks
There are many different patterns that you may want to search for in logs to identify potential cyber security attacks. Some common patterns to look for include:
- Brute force login attempts: Attackers may try to guess the login credentials for a system by trying different combinations of username and password. You can search for repeated failed login attempts from the same IP address to identify potential brute-force attacks.
- Suspicious network activity: Large amounts of incoming or outgoing traffic from a single IP address, or sudden spikes in traffic, may indicate that an attacker is trying to access the system or is using it to launch an attack on other systems.
- Malware infection: If you see evidence of malware infections, such as strange processes running or files being created or modified, this may indicate that the system has been compromised.
- Unauthorized access: If you see evidence of unauthorized access to the system, such as login attempts from unusual locations or attempts to access restricted resources, this may indicate that an attacker is attempting to gain access to the system.
It is imperative to note that these are just a few examples of patterns that you may want to search for in logs. There are many other indicators of potential cyber security attacks that you may need to consider, depending on the specific threat landscape and the vulnerabilities of your systems.
