Introduction to Wireless Intrusion Detection Systems

Security in IT systems is an increasingly important area of research as users have come to accept that every system connected to the Internet is vulnerable. These vulnerabilities can come from known threats, zero-day attacks, malware, or DoS (denial of service) attacks. Some systems that aim to protect against these attacks include firewalls and antivirus systems. Each of these defenses only covers a fraction of computer security however. Firewalls are barriers and do not inform about activity within the network while antivirus systems only protect against malicious software on hosts. There are many more protocol and network level threats, which these options do not protect against.
