\nEvery enterprise network is vulnerable to threats such as unauthorized access, data breach, modification, and exploitation. An IT infrastructure that secures the network from such threats is called network security.<\/p>\n
\nThis question can be answered by the fact that cyber threats are proliferating at an exponential rate. The present day security threat to any enterprise IT has surpassed its ancestors by light years. Cyber threats of today are multi-faceted, sneakier, and technologically more advanced. Some of the most common types of threats to network security include:<\/p>\n
\nAPTs are threats that keep a low-profile to stay hidden, and are highly persistent in their attacks. Such attacks are slow but recurring in nature. They may stay hidden in the compromised network and wait for the right moment to strike.<\/p>\n
\nSpyware are software that secretly steals sensitive information from the victim\u2019s computer. Adware are software that display unwanted advertisements on the compromised machine. Sometimes, adware are classified as a type of spyware because they track user\u2019s personal information and send it to a third party without the user\u2019s knowledge.<\/p>\n
\nUnarguably, the weakest link in IT security is the human element. One phishing email, one unaware user and one click is all it takes for a hacker to take down the entire network of an organization.<\/p>\n
\nAn attacker\u2019s attempt to exploit a known but still unpatched security vulnerability is known as a zero-day attack. It is also known as a zero-day exploit.<\/p>\n
\nDoS attacks are classified as one of the most critical types of targeted attacks against enterprise IT network. Such attacks are crafted to flood a targeted network by useless traffic (more requests than the server can handle<\/em>), so that it becomes unavailable or inaccessible to its intended users.<\/p>\n
\nSuch attacks are deployed by an attacker to intercept information that takes place between computers in the targeted network. With such attacks, the attacker can monitor, record, and even control the relay of communication.<\/p>\n
\nWhen we speak of network security, we are referring to a solution that offers multiple layers of protection. This is to ensure that if one layer is down, other layers are still there to stop an attacker from advancing any further. In other words, the more the layers of security, the lesser the opportunity for attackers to get in and out of the network.<\/p>\n
