Cyber security is the technique of preventing harmful assaults on computers, servers, mobile devices, electronic systems, networks, and data. It’s often referred to as electronic information security or information technology security.
1. Conduct awareness and training on cyber security.
Employees must be educated on issues such as cyber security, corporate regulations, and incident reporting in order for a solid cyber security strategy to succeed. Employees’ inadvertent or malicious malevolent activities can cause even the greatest technical safeguards to fail, leading to an expensive security breach. The most effective strategy to reduce negligence and the risk of a security breach is to educate staff and raise understanding of corporate policies and security best practises through seminars, lectures, and online courses.
2. Evaluate the risks.
Organizations should do a comprehensive risk assessment to identify all important assets and prioritise them depending on the impact that a compromised asset will have. This will assist businesses in determining how best to spend their resources on safeguarding each valued asset.
3. Ascertain vulnerability management and software patch/update management.
To limit threats to corporate IT systems, it is critical for organisational IT teams to execute vulnerability detection, classification, remediation, and mitigation across all applications and networks they utilise. Furthermore, security researchers and attackers occasionally discover new vulnerabilities in diverse applications, which are disclosed to software providers or made public. Malware and cyber criminals frequently take advantage of these flaws. Patches and mitigations for these vulnerabilities are released by software vendors on a regular basis. As a result, keeping IT systems up to date aids in the protection of organisational assets.
4. Make use of the least privilege principle.
According to the idea of least privilege, both software and employees should be given the fewest permissions essential to do their tasks. This reduces the impact of a successful security breach by preventing lower-level user accounts/software from affecting valuable assets that require higher-level authorization. All high-level user accounts with unrestricted access should also employ two-factor authentication.
5. Secure password storage and practises should be enforced.
All employees should be required to use strong passwords that comply to industry approved standards. They should also be required to be changed on a regular basis to guard against password breach. Furthermore, the use of salts and strong hashing techniques should be followed when storing passwords.
6. Create a solid business continuity and incident response plan (BC-IR).
With solid BC-IR strategies and practises in place, an organisation can efficiently respond to cyber-attacks and security breaches while ensuring vital business systems stay operational.
7. Conduct regular security audits.
Periodic security inspections of all software and networks aid in the early detection of security risks in a secure environment. Application and network penetration testing, source code reviews, architecture design reviews, and red team assessments are all examples of security reviews. Organizations should prioritise and mitigate security vulnerabilities as quickly as feasible after they are discovered.
8. Backup your data
Backing up all data on a regular basis will increase redundancy and ensure that no sensitive data is lost or compromised in the event of a security breach. Attacks such as injections and ransomware, compromise the integrity and availability of data. Backups can help protect in such cases.
9. Encrypt data while it’s in transit and at rest.
Strong encryption algorithms should be used to store and transfer all sensitive data. Data secrecy is ensured by encrypting it. In addition, effective key management and rotation rules should be implemented. SSL/TLS should be used by all web apps and software.
10. Create software and networks that are secure.
Always consider security when developing apps, writing software, and designing networks. Remember that rewriting software and adding security measures later is much more expensive than integrating security in from the start. Applications with security features decrease dangers and ensure that when software or networks fail, they do so safely.
11. Use industry-standard input validation and secure coding practises.
Against many sorts of injection attacks, strong input validation is frequently the first line of protection. Strong input validation helps screen out harmful input payloads that the application would process because software and applications are built to receive user input. Furthermore, when designing software, secure coding standards should be followed to avoid the majority of the vulnerabilities listed in the OWASP and CVE databases.
Cybersecurity‘s Importance and Challenges
Given the rapidly changing technological landscape and the fact that software adoption is increasing across a wide range of industries, including finance, government, military, retail, hospitals, education, and energy, to name a few, more and more information is becoming digital and accessible via wireless and wired digital communication networks, as well as the ubiquitous internet. To thieves and evil doers, all of this highly sensitive information is quite valuable, which is why it is critical to safeguard it with strong cyber security systems and processes.
In the recent severe safety violations of Equifax, Yahoo and US Securities and Exchanges Commission (SEC), which have lost great sensitivity in user information, which have damaged their reputations and finances irreparably, the need for a strong cyber-security strategy is apparent. And, as the pattern implies, the number of cyber-attacks is on the rise. Attackers target both large and small businesses on a daily basis in order to obtain sensitive information or disrupt services.
The same changing technology landscape presents obstacles in the implementation of efficient cyber security policies. When it is updated and upgraded, software is constantly changed that creates and opens up new issues and vulnerabilities to different cyber attacks. Further, with many firms now transferring their on-site systems to the cloud, IT infrastructure is evolving, which presents a whole new set of design and execution difficulties, creating a new category of vulnerabilities. Companies do not know the different threats inside their IT architecture and hence cybersecurity remedies cannot be implemented until much too late.
