What is IT Security?

IT Security is used to protect a company’s data against potential threats and damage. It prevents third parties from hacking into a firm’s database, then being able to manipulate their data and systems. Organisations adopt cyber security strategies for protection against hackers and to help businesses be more structured, organised, and improve their practices. This allows them to manage potential cyber-attacks in a more sophisticated way.


Why is IT Security so important?

Having weak IT Security puts your business at risk. Unauthorised organisations can easily access your data, steal from you, or your data can get lost due to a lack of action in protecting your information. This inaction can cost companies money and even customers. Prioritising CIA (confidentiality, integrity, and availability of data) protection and protecting client data is crucial. Investing in reliable IT Security is important because all businesses need protection from cyber threats and security attacks.


What is the main purpose of IT Security?

Sensitive data has become more valuable in recent years. As briefly mentioned, CIA must be protected at all costs. Additional parts of IT Security that must be maintained are accountability, authenticity, non-repudiation, and reliability.


Confidential data

Confidential information must only be accessed by authorised people within the company. The individual or group of people must be defined before assigning them access rights to the data. Transportation of information is another key area and must be encrypted. Having designated individuals authorised for data access and transporting data means no unauthorised people can use the company’s systems.


The importance of User Security

User Security is a vital element of IT security. If unaware of its importance, employees may be putting themselves and the business at risk of cybercrimes, phishing, and other social-engineering attacks. A company IT team can support users in protecting themselves. They can provide training to staff and help identify, avoid, and report potential threats, which may expose sensitive data. Organisations can test users with mock phishing and other attack simulations. This can help employees become accustomed to implementing best practices in regard to security, increase their awareness, and develop a good security mindset.


What are the main areas of IT Security?

Endpoint security

Every device must have endpoint security, including related applications and operational systems. Endpoint security is securing endpoints or the end-user of equipment such as laptops, desktops, and smartphones. Endpoints act as points of entry to a company’s network. Points of entry are created, which can then be exploited by hackers. Endpoint security protects all that is within the company network and protects points of entry from malicious attacks. Enterprises must ensure they’re endpoint compliant with the latest data security standards.


Cloud Security 

Cloud security can help prevent the loss of important information, data leakages, and data being stolen by scammers. Data is stored online via a cloud computing platform. Cloud security is important as more businesses are going to be transferring their data centres, processes, and applications over to the cloud. Businesses should ensure strong security policies are in place, enforce a company culture of security, and implement cloud security solutions properly to help prevent attacks.


Protection from Cyber Attacks 

When IT security is compromised, this can bring severe consequences for businesses. Criminals can forge fake identities, and misuse data or credit information because they have access to personal information.

Cybercrimes are always innovating, finding new opportunities, and looking for security loopholes to take advantage of. All it takes is a single weakness for offenders to take down a company’s systems and compromise its data. Here are some protection methods companies can use:

Install malware protection software

Limit the amount of information you share online

Set up firewalls and internet gateways

Secure configuration on every device, operating system, and application

Use appropriate and complex passwords

Control access for users – limit permissions


IT Security Summary

The three components of CIA must be met otherwise there can be disastrous consequences. Cybercrime is prevalent now more than ever, so having robust IT Security is a necessity.
