What is IT security and why is it important?

Content Writer

Setting up locks and alarm systems for offices is a no-brainer. But conventional security measures like these only protect physical assets. Digital assets like networks and databases require a different kind of security: IT security. With the growing number of cyber attacks, IT security has become critical for every modern business. Here’s everything you should know.

What are the threats?

IT cyber security threats have evolved significantly, posing a serious challenge to information technology security. Common threats include:

  • Ransomware. Hackers use ransomware to encrypt an entire device, network, or database. Then they demand a ransom to be paid for access to be restored.

  • Spyware. Malware that illegally collects internal business data is called spyware. It can sit on company devices for a long time without being detected, which makes it especially dangerous.

  • Phishing. Phishing happens when hackers fabricate messages to steal sensitive information. For example, an employee may receive a fake email asking for login credentials to an important business account.

  • DDoS attack. A DDoS attack occurs when hackers flood company servers with thousands of bots to overwhelm them and shut them down.

Cyber threats may differ in their form, but they all inflict damage. Getting hacked can lead to seized data (in the case of ransomware), breached data, and a halt in business operations. At best, cyber attacks will result in minimal monetary losses. At worst, your business will be forced to shut down. That’s why IT cyber security should be a priority.

Types of IT security

A company’s digital infrastructure comprises many different parts, which calls for several types of IT security:

Internet security

The beauty of the internet is that it’s accessible to everyone. This also means it’s accessible to hackers. They can plant malicious links, target victims through unencrypted websites, or perform DDoS attacks. The result can be stolen credentials, leaked data, or a crashing website. To improve your business’s internet security, use:

  • Encryption. With encryption tools, confidential data is scrambled with a special encryption key, making it inaccessible to outsiders. Using a VPN is one of the easiest ways to encrypt all of your internet traffic.

  • Strong passwords. Strong passwords are a must to protect online accounts against cyber attacks. The NordPass business password manager is an excellent tool to secure accounts effortlessly.

Endpoint security

Endpoints are all of the devices connected to the same network. In a company, the endpoints are all laptops and cell phones of employees. Hackers can target separate endpoints to gain access to the whole network. So a business’s network security is fully dependent on how secure the endpoints are. IT security services like antivirus software and a firewall can help secure them.

Cloud security

Cloud computing has allowed companies to store, manage, and access data quickly and easily. It has eliminated the need for middlemen when transferring data and has optimized most business operations.

However, the risks to data stored on the cloud are far greater than those of conventionally stored data because cloud computing operates over the internet (we’ve already covered internet security risks). Cloud security seeks to overcome these threats by encrypting data and filtering traffic.

Application security

Businesses operate through many different applications. From browsers to websites to mobile apps, they all have vulnerabilities. Application security aims to protect all of these from outsiders. To secure your web application, you should:

  • Use a secure hosting provider like Hostinger

  • Get an SSL certificate to encrypt all incoming and outgoing data on the website.

  • Use CAPTCHA to detect DDoS bots.

User security

Although IT security takes place in the digital world, it all comes down to people. In business, “people” means employees. IT security should be a team effort with all members on board. To increase user awareness and security, educate employees on all IT security threats and countermeasures. Encourage them to use cybersecurity tools responsibly and to report any suspicious activity.

What is information security risk management?

Information security risk management (ISRM) is an essential subset of IT security risk management. Its main purpose is to guide organizations in identifying, managing, and mitigating potential threats to their valuable information assets. Given the rising prevalence of cyber threats and data breaches, the value of a well-structured ISRM strategy is high.

Adding another layer of defense, ISRM contributes to building a resilient and secure IT infrastructure that is capable of withstanding the ever-evolving cyber threats. It's more than just a technical process - it involves the collaboration of various departments and stakeholders, reinforcing the idea that security is everyone's responsibility. Ultimately, the goal of ISRM is to ensure the confidentiality, integrity, and availability of an organization's data. It enables smooth operations, safeguards customer trust, and reinforces the company's reputation in the long term.

Enterprise IT Security

Enterprise IT security is a comprehensive approach employed across an organization to safeguard its crucial information assets from cyber threats. By employing enterprise IT security solutions, businesses effectively shield their digital infrastructure from malicious activities. This practice encapsulates a range of measures, from robust security systems to custom IT solutions designed to fend off cyber-attacks.

Furthermore, enterprise risk management in IT security plays a pivotal role in this strategy. It aids in identifying, assessing, and prioritizing risks, which can then be addressed by implementing appropriate countermeasures. This proactive approach ensures that the organization is well-prepared for potential cyber threats, thereby minimizing potential disruptions or damages.

The ISRM process for an enterprise typically includes four key stages:

  • The first stage involves identifying valuable assets and their associated risks. They could include anything from databases and software to hardware and intellectual property.

  • The second stage, risk assessment, prioritizes these identified risks based on their potential impact and likelihood of occurrence.

  • The third stage, risk mitigation, involves the formulation and implementation of strategies aimed at reducing the impact of high-priority risks. This might involve preventative measures such as the implementation of firewalls or antivirus software, as well as incident response plans.

  • The final stage, evaluation, and maintenance, is an ongoing process of monitoring and reviewing the effectiveness of risk management strategies. This ensures the strategies remain relevant and robust as business operations evolve and new threats emerge.

BIT Security for Small Business

Small businesses, while a significant part of the economy, often face a unique set of vulnerabilities when it comes to IT security. One common misconception is that smaller organizations are less likely to be targeted by cyber threats. In reality, due to limited resources and lack of robust IT security measures, they often become an easy target for cybercriminals. This makes cybersecurity for small business a crucial issue that needs addressing.

Several threats specifically target small businesses. These include phishing attacks that seek to trick employees into revealing sensitive information, ransomware that encrypts critical data and demands a ransom for its release, and data breaches that exploit weak security to steal customer and business data.

Other threats include insider attacks, often unintentional, resulting from poor security practices by employees, and DDoS attacks aimed at overwhelming and crashing business websites.

Given these vulnerabilities, IT security for small businesses is not an option, but a necessity. Here are the top five cybersecurity tips for small businesses:

  1. Employee training: Educate employees about safe online practices and how to identify phishing emails or malicious links.

  2. Regular backups: Regularly backup critical data to recover from ransomware attacks or data loss scenarios.

  3. Robust authentication: Implement strong password policies and consider multi-factor authentication for added security.

  4. Update and patch: Keep all systems, software, and applications updated to fix security vulnerabilities.

  5. Incident response plan: Develop a response plan to manage and minimize the impact of a cyber attack when it occurs.
