What are the four categories of DOS attacks?
Types of DOS:
- Volumetric attacks: This is an Attack where the entire bandwidth of a network is consumed so the authorized clients will not be able to get the resources.
- Syn flooding:
- Fragmentation attacks:
- TCP-State exhaustion attack:
- Application Layer Attacks:
- Plashing:
What are the three categories of DOS attacks?
Broadly speaking, DoS and DDoS attacks can be divided into three types:
- Volume Based Attacks. Includes UDP floods, ICMP floods, and other spoofed-packet floods.
- Protocol Attacks. Includes SYN floods, fragmented packet attacks, Ping of Death, Smurf DDoS and more.
- Application Layer Attacks.

When to consider security considerations on SIP trunks?
When considering security on SIP trunks, you need to take into account different aspects of security. These aspects call for a series of features and capabilities to mitigate the potential threats. Security is always best deployed in a layered architecture, rather than a single box or feature that strives to protect against all possible attacks.
How to determine if SIP inspection is configured on Cisco ASA software?

How is CUCM used to deny SIP traffic?
On devices in your network that should not run SIP traffic at all, the Control Plane Policing (CoPP) feature can be used to deny all SIP traffic. CUCM has (by default) a feature that restricts traffic on a SIP trunk to be accepted only from the IP address configured on the SIP trunk.
