What Are The Biggest Threat To The Security Of a Computer Network
One of the biggest threat is privilege escalation, which is a network intrusion that takes an advantage of the programming errors or design flaws. Virus is another threat that can cause damage to the computer network and can also affect the user’s privacy . A self replicating malware called worms, can affect the computer security as it will slowly consume the system resource and will halt other tasks. Trojan horse is another common threats, they are hidden in some innocent locations such as screensavers, e-mails etc. Spyware collects all the type of data, they can be personal information, and user logins.
