Cyber defense protects information and most important assets against attacks [fsecurity]. Cyber defense is tied in with enabling an organization to thwart digital assaults through network safety. It includes all cycles and practices that will shield an organization, its information, and hubs from unapproved access or control. The most common cyber defense activties includes the following:
- Installing or maintaining hardware and software infrastructure that deters hackers
- Analyzing, identifying and patching system vulnerabilities
- Real time implementation of solutions aimed at diffusing zero-hour attacks
- Recovering from partially or fully successful cyber attacks [ECPI edu]
These activities are some of the defense activities that helps an organization to manage risks and defend its information against any external attacks.
As per force point, the elements that play in important role in Defense in Depth or DiD are network security controls, antivirus software, analyzing data integrity, and behavioral analysis. Each of these elements of significance in cyber defense.
Network security controls
The first line of defense when securing a network is the analysis of network traffic. Firewalls prevent access to and from unauthorized networks and will allow or block traffic based on a set of security rules. Intrusion protection systems often work in tandem with a firewall to identify potential security threats and respond to them quickly. [Forcepoint]]
Antivirus software is critical to protecting against viruses and malware. While these arrangements offer solid assurance against malevolent programming, signature-based items can be misused by clever cybercriminals. Hence, it is wise to utilize an antivirus software that incorporates heuristic highlights that check for dubious examples and movement. [Forcepoint]
Each file on a framework has what is known as a checksum. This is a numerical portrayal of a record that shows the recurrence of its utilization, its source and which can be utilized to check against a known rundown of infections and different vindictive code. On the off chance If an incoming file is completely unique to the system it may be marked as suspicious. Data Integrity can likewise check the source IP address to guarantee it is from a known and confided in source. [Forcepoint]
Files and organization practices frequently give understanding while a breach is in progress or has happened. On the off chance the examination is enacted, it implies the firewall or interruption assurance arrangements have fizzled. Behavioral analysis gets a move on and can either send cautions or execute programmed controls that keep a break from proceeding with any further.
According to security magazine, the insights the top five insights for cybersecurity defense have been summarized as follows:
1. The bad guys are more active than ever.
2. Ransomware attacks and payments continue to rise.
3. People are the biggest problem.
4. IT security is having some successes.
5. Advanced security analytics and machine learning are becoming “must-haves.”
These insights go on to prove that with time, the need for cyber defense will become paramount immaterial of the industry being IT, healthcare or business. There should be more awareness campaigns and regular trainings offered to security professional not only to protect and prevent but also defend.
