Which tool can identify a malicious traffic by comparing packet contents to know attack signatures?A signature-based intrusion detection system (SIDS) monitors all the packets traversing the network and compares them against a database of attack signatures or attributes of known malicious threats, much like antivirus software.
Which tool can perform real time traffic and port analysis and can also detect port scans fingerprinting and buffer overflow attack?Snort is an open source intrusion protection system (IPS) that is capable of performing real-time traffic and port analysis, packet logging, content searching and matching, as well as detecting probes, attacks, port scans, fingerprinting, and buffer overflow attacks.
What protocol is used to collect information about traffic traversing a network?NetFlow is a protocol used to collect metadata on IP traffic flows traversing a network device. Developed by Cisco Systems, NetFlow is used to record metadata about IP traffic flows traversing a network device such as a router, switch, or host.
Which type of attack allows an attacker to use a brute force approach?The most basic brute force attack is a dictionary attack, where the attacker works through a dictionary of possible passwords and tries them all.
