The state of network security
David E. Schneider · Network Security · 2012
Security is a discipline concerned with protecting networks and computer systems against threats such as hacking exploits, malware, data leakage, spam and Denial of Service (DoS) attacks, as well as ensuring trusted access through mechanisms such as IPsec or SSL. Enterprises have deployed security devices of all types to defend against threats, and to prevent unintended data leakage. But what does the threat landscape really look like today? And how are we dealing with these threats? This may be a good time to step back and take stock of where IT security stands right now.
