Indicators of Attack
Indicators of Attack (IoAs) provide early warnings of potential threats by identifying suspicious activities or behaviors within a network, thereby helping organizations proactively defend against cyberattacks. The following are some common indicators that will help you identify attacks:
- Account lockout: Account lockout serves as an early warning sign that something is wrong. Frequent or unexpected lockouts, especially for privileged accounts, could indicate malicious attempts to gain unauthorized access. A brute-force attack, for instance, will lock accounts out as most companies only allow three attempts.
- Concurrent session usage: Monitoring the number of concurrent user sessions can reveal suspicious activity. Sudden spikes or a significantly higher number of concurrent sessions than usual might indicate unauthorized access or a breach in progress.
- Blocked content: Attempts to access valuable data can be revealed by blocked content indicators...
