Data and Network Security

In 2021, a report by the JPMorgan International Council was disclosed, urging public and private actors to intensify their cybersecurity efforts to combat a dangerous rise in cybercrimes that poses a threat to national security and the economy. In fact, the council referred to cyberspace as the most dangerous weapon globally!

It can be used against individuals, families, societies, private and public enterprises, and even the government. Hence, the IT network monitoring team must effectively secure resources on a network from being accessed by unauthorized users, devices, or groups.

To secure a network and cut down on the loopholes hackers can easily leverage to break your network defenses, you must understand common network security vulnerabilities and how business owners are staying secure here: 

As most organizations are practicing the hybrid system, these common vulnerabilities don’t just concern the office workforce alone but remote too, and they include

  • Weak or absence of physical security.
  • Weak password
  • Hardware and/or software operating systems not adequately installed.
  • Software and/or software operating systems are installed but not regularly updated to meet the latest security conditions.
  • A design flaw in an operating system and the network.

Datacenter security is evolving very fast. The need for data center security solutions results from continuous dependence on cloud computing, ever-changing requirements for network regulations, and intense sophistication in threats and cyberattacks.

There are some common types of cyberattacks you must know about and the steps you need to ensure data and network security. There are also tools you’ll need to know about to boost your security architecture and how you can equip your employees to prevent and avoid security breaches.

Common Types of Cyber Attacks

Regardless of whether your network holds a massive volume of data or serves as the backend of your most essential services, they remain juicy spots for cybercriminals to attack. Here are the common types of cyberattacks to be aware of:

DoS And DDos Attacks: Denial-of-service (DoS) and distributed denial-of-service (DDoS) attacks burden an organization’s system and make it hard to respond to service requests. It is often directed to a system from multiple computers with junk and crafted requests to occupy the system with handling unwanted data instead of the required tasks.

Common DoS.and DDoS types include Smurf attack, TCP SYN, teardrop attack, botnets, and ping-of-death attacks.

Phishing Attacks: Phishing attacks involve directing attacks to a network via emails disguised as legit but aim to steal information or manipulate the network. It could mean unknowingly downloading an attachment in an email or an illegitimate website automatically that loads malware into your computer.

Ransomware Attacks: Attackers encrypt essential data in a computer when access is gained to prevent the administrator from accessing them. Victims who do not have data center backups are forced to pay a ransom before the files are restored.

Password Attacks: Password attacks are the commonest types used in authenticating users’ identities. Passwords are obtained through various means, including utilizing keyloggers, screen recording software, eavesdropping, leveraging password databases, or outright guessing.

Password guessing by testing different passwords randomly, hoping that one will finally work, is called Brute-force attacks.

Man-in-the-middle (MitM) Attacks: In this kind of attack, an attacker positions himself between two victims or a victim and a server to siphon sensitive information So, you can learn all the above mentioned topics about the cyber attacks and solutions to stop attacks and secure your data by enrolling in this CCSP Training Course.

7 Steps to Data and Network Security

As network and data attacks continue to increase, organizations must secure their businesses by blocking out vulnerabilities in the system and frustrating the efforts of malicious attackers. These steps to data and network security should be considered.

1. Maintain and Update Software, Configurations, and Firmware Often  

Software is regularly updated to meet security demands. By updating your software often, you’ll have stepped up your security capabilities to combat threats. In addition, changing your passwords often can prevent security breaches.

2. Prioritize Physical and Environmental Security of Network Infrastructure

Your network’s physical and environmental security should be considered vital aspects of your security considerations. There is a possible intent by an insider or outsider to gain access to your network physically.

3. Audit Your Security Architecture

It is crucial to know precisely what kind of security issues you are dealing with to be able to prevent them. Audit periodically to access information on potential threats that might be ongoing within the system.

4. Design an Infrastructure Framework

Designing a framework for organizational infrastructure can help detect vulnerabilities and entry points. Understand how your network is accessed to make it easy to track down irregularities while troubleshooting.

5. Integrate Comprehensive Encryption and Authentication Practices into The Network

Authentication Practices are part of your first-line defense strategies and one of the most effective. Encryption makes it difficult for an intruder to access or use data on your network. The administrators must effectively utilize both practices.

6. Security Policies Must Be Duly Understood

Every user gaining access to a network must understand the network policies and the required behaviors to uphold security. For instance, passwords must include uppercase letters, lowercase letters, numbers, and special characters to make them strong.

7. Have a Backup Plan

What if your network security measures fail? Your company should have an escape route to sustain it from total collapse. Have a backup strategy to help you minimize losses and avoid interruptions in business operations.
