This enables various network attacks it unreliable or unusable. UCSD. Network attacks are defined as a set of malicious activities to disrupt, deny, or destroy information and service resident in computer networks CS Lecture NotesNetwork Attacks Problem: SSL stripping Common use pattern: user browses site with HTTP, upgrades to HTTPS for checkout. Integrity: No one can manipulate our data/communications unless we want them to Network attacks can be categorized into a few broad types as listed below from most local to least localPhysical Access: The attacker has physical access to the networkIn Path/Man in the Middle: The attacker is between a communicator and the intended recipient and can see, add, and block packets A stack overflow attack on the BIND program, used by many Unix and Linux hosts for DNS, giving immediate account access. Vulnerable CGI programs on servers, often supplied by the vendor as sample programs and not removed. We will put our focus mainly on the network attacks happened around the TCP/IP (Transmission Control Protocol/Internet Protocol) protocol suite, which is the most Lecture Network Attacks. Local attacker can race real server for response, set victim’s network gateway We will put our focus mainly on the network attacks happened around the TCP/IP (Transmission Control Protocol/Internet Protocol) protocol suite, which is the most widely of network attacks. Winter Material from Deian Stefan, Stefan Savage, David Wagner, and Nick Weaver. Nadia Heninger. Local attacker can race real server for response, set victim’s network gateway and DNS server to attacker-controlled values Recall: DHCP used to configure hosts on network. Basic security goals: Confidentiality: No one should be able to read our data/communications unless we want them to. Network attacks generally adopt computer networks as transportation media to convey the intrusion or even attack the communication system itself. DHCP requests broadcast to local network. CGI program flaws are the common means of taking over and defacing servers CS Lecture NotesNetwork Attacks Problem: Bad certificate If a certificate is bad/unknown, browser issues warning dialog: Most users can't understand, so they just click OK. Some browsers warn repeatedly, but users will still just click through. Active network DHCP requests broadcast to local network.
