A Public Switched Telephone Network (PSTN) offers basic security through traditional measures such as circuit-switching and limited access control, which make it difficult for unauthorized users to tap into calls. However, the security of PSTN is generally considered weaker compared to modern digital communication systems, as it is vulnerable to interception and eavesdropping. Additionally, PSTN lacks encryption by default, making it susceptible to various forms of attacks. Overall, while it provides some level of security, it is not sufficient for highly sensitive communications.
