Most businesses these days are driven by technology because it is quick, and it increases the reach of the business. But due to increasing technological dependency, the cases of a security breach or Cyber-attacks have increased too! And no business would want their informational asset to be leaked or breached.
Hence, organizations these days are investing in proper frameworks that help in information security. Obviously, it is better to invest in security than to lose money due to a breach. And this is where Information security management comes into the picture. Let’s discuss what is information security management?
In this Article:
Information Security Management (ISM) narrates a set of controls and policies that organizations implement to secure their information assets from attacks, threats, or vulnerabilities. Many firms develop a documented procedure for managing information security or InfoSec. This is termed as Information Security Management System (ISMS).
There are three security objectives or goals to provide management support and direction for information security according to the business requirement and relevant rules. The three security controls to protect information at the organization level are known as the CIA triad and are explained below:
1. Confidentiality: Confidentiality or privacy of information means that certain protected information is open to only authorized personnel. The security measures as per the information security management system allow only these people to fetch or modify the data. The security team classifies data according to perceived risk and calculates the impact of the data if it gets compromised. For high-risk data, additional privacy controls are put.
2. Integrity: The information security management system manages data integrity by putting controls to ensure the accuracy and consistency of stored data through its lifecycle. Measures such as user access controls, version controls, and checksums provide better integrity.
3. Availability: Proper steps are taken by the ISM team to ensure the timely availability of data to authorized personnel only. Typical InfoSec activities are followed if Cyber-attack occurs. They include proper hardware maintenance, patch installation and upgrade, implementing disaster recovery procedures, and incident response.
ISMS defines a set of procedures or processes to manage data risk like hacks, Cyber-attack, data theft, or leak. ISO 27001 is the international information security management standards which provide the requirements and specifications to implement ISMS. Following are the benefits of the information security management system:
The international information security leader is ISO 27001. But other frameworks set a good information security management system example. These borrow from ISO 27001 and may contain some organization-centric guidelines too. These standards are:
Our dependency on the internet, information and electronic devices has increased considerably in recent times. This has helped the organization to process the information faster, more efficiently and effectively. But it has brought some serious challenges and threats to protect information. It has become important for firms to protect their critical information from getting into the wrong hands.
According to a global information security survey by the giant E&Y in 2010, in 46% of cases firms have reported an increase in investment in information security. The report also indicates that 60% interviewees feel that the use of cloud computing, smartphones, social media and other personal gadgets have posed a higher risk to information security. However, a firm must keep a proper mix of managerial, behavioural and technical aspects of information security to overcome the data risk challenges.
There have been multiple case studies done in the past to study about information security management system and its need. The case study on information security management with examples brought into light that information security is a separate discipline which contains numerous dimensions like technical security, operational security, application security, mobile security and behavioural security. Various ISM Case studies performed by different authors in the past with their key findings are mentioned below:
Following are the importance of information security management set up in an organization:
So now it is clear that to survive in this technology-driven world, both small and big organizations need to implement ISMS. Maintaining data security is a must and plans to mitigate threats should be ready at hand. Seeing the importance of data security, people are going for information security management certification. This increases career opportunities for professionals and lets them prove expertise in incident and risk management. So, if this field appears appealing to you, go ahead and become a certified information security manager.
