Why Information Security Is Needed?
Information security is to preserve the confidentiality, integrity, and availability of information. Also, information security is about protecting information.
However, it is not only about the protection of information. It also deals with how to protect the confidentiality, integrity, and availability of information.
Confidentiality means that it should be from being to unauthorized parties. Integrity means that it should be from being by unauthorized parties. Also, availability means that it should be available to authorized parties.
Five-Step Approach to Protecting Information Security
The five-step approach to protecting information is as follows.
- 1. Identify the assets that need protection.
- 2. Identify threats to those assets.
- 3. Determine the vulnerabilities of those assets.
- 4. Determine the likelihood and impact of those threats and vulnerabilities.
- 5. Mitigate by determining countermeasures and implementing them in your environment.
- Identify the asset that needs protection:
The first step is to identify the asset that needs protection; we need to identify what we want to protect first. Next, we need to identify the asset, which is valuable enough for us to protect it from any potential threats or vulnerabilities, including internal and outside threats.
- Identify the threat to the asset:
After identifying the asset, we also need to identify what kind of threat can damage the asset. Also, the next step is to identify the type of threat that can damage this asset.
The most common types of threats are internal threats and external threats. Internal threat is the threat that comes from inside this organization, while external threat is the threat that comes from the outside or external environment.
- Identify vulnerabilities of the asset:
The next step is to identify what kind of vulnerabilities can affect this asset. Also, the next step is to identify the type of vulnerability that will affect this asset, so we have to identify what kind of vulnerability can be by these threats.
- Determine the likelihood and impact of these threats and vulnerabilities:
The fourth step is to determine what kind of likelihood and impact can be by all these threats and vulnerabilities. The next step is to determine the likelihood that this threat can exploit this vulnerability, and then determine the impact that will occur if this happens.
It is likely because it explains how likely the threat can exploit the vulnerability. Also, it impacts because it explains what kind of impact will occur if the threat exploits the vulnerability.
- Then, we have to mitigate them:
The last step is to mitigate them by determining countermeasures and implementing them in your environment.
Information security is very important for many reasons. First, confidentiality, integrity, and availability of information are very important for organizations. Next, it is by regulation. Finally, it is by law.
Drawbacks
Not all organizations are in information security. One of the reasons why information security is is to preserve the confidentiality, integrity, and availability of information.
However, it is not only about the protection of information. It also deals with how to protect the confidentiality, integrity, and availability of information. The first reason why information security is is to protect digital data.
When an organization has confidential data stored on its systems but does not have any kind of protection on that data, it can be a risk for that organization. If this data gets stolen, the organization might suffer some losses.
Conclusion
In conclusion, information security is to preserve the confidentiality, integrity, and availability of information. Also, it is about how to protect the confidentiality, integrity, and availability of information.
