Security Threats Overview
Deploying improved network security nowadays is more important than ever. Many companies in various industries have fallen victim to attacks in the past and lost important private data and intellectual property. To make things more dangerous, attackers are not limited to individuals or small teams of hackers only but also organized crime and national governments are sometimes involved.
Attackers are getting smarter and use creative techniques to produce unique new threats. As a result, network engineers must be prepared to think outside the box and respond to the ever-changing threat landscape. Understanding key security concepts, such as threats, vulnerabilities, exploits, risks, and mitigation techniques, can help defend against attacks.
A security threat to a network refers to any activity or event that has the potential to compromise the confidentiality, integrity, or availability of the network or its resources. Many types of security threats can affect a network.
Some of the most common ones include:
- Malware
- Hacking tools
- DoS and DDoS
- Amplification attacks
- Social engineering
- Phishing
- Spoofing attacks
- Man-in-the-middle attacks
- Password attacks
- Reconnaissance attacks
It's important to have a comprehensive security strategy that includes firewalls, intrusion detection systems, and regular security audits and training for users. The impact of a threat can vary depending on the type and severity of the attack and the level of security measures in place to prevent or mitigate it.
