Disadvantages of IPSec
- Configuration complexity: IPSec can be complex to configure and requires specialized knowledge and skills.
- Compatibility issues: IPSec can have compatibility issues with some network devices and applications, which can lead to interoperability problems.
- Performance impact: IPSec can impact network performance due to the overhead of encryption and decryption of IP packets.
- Key management: IPSec requires effective key management to ensure the security of the cryptographic keys used for encryption and authentication.
- Limited protection: IPSec only provides protection for IP traffic, and other protocols such as ICMP, DNS, and routing protocols may still be vulnerable to attacks.
IP security (IPSec)
Pre-Requisite: Types of Internet Protocol
IP Sec (Internet Protocol Security) is an Internet Engineering Task Force (IETF) standard suite of protocols between two communication points across the IP network that provide data authentication, integrity, and confidentiality. It also defines the encrypted, decrypted, and authenticated packets. The protocols needed for secure key exchange and key management are defined in it.
