A Guide to Cyber Security for Business

It is a normal day in 2024, a shadowy figure sits in front of his computer waiting for just the right person to click on the wrong link. This is a scene that we have seen a lot on TV; however, it is actually not far from the truth. Still, at least on TV, the scene looks exciting. Unfortunately, in real life, not so much. In 2025, a hacker managed to paralyse the American healthcare system by shutting down the system of a middleman company that handles bills, procedure approvals, and medicine approvals. The effect was instant! Thousands had to reschedule their appointments and wait more than needed for a simple prescription. 

Cyber attacks are no longer just an exciting plot for a movie; they are real. Therefore, you have to be ready for them. As long as you are a business owner with access to user data, you need to understand how to secure your company against attacks. Therefore, here is your guide to cyber security for business.

The Basics of Cyber Security For Business 

What is Cyber Security?

The term cyber security describes the techniques used to secure various data. These techniques include protection against malware, viruses, or human errors. They could also include protection from a DoS attack that shuts down a whole system or ransomware that demands money to release your data. Which level of security you need depends on the size of your company and the type of data you store. 

Even for start-ups, there is a need to invest in cyber security to an extent. Hire an expert if you are not sure of your next step. A cyber security expert can help you learn about security pillars and types of cyber attacks. He can also ensure your staff is trained well-enough to avoid human error.

Security Pillars

Network Security 

Network security basically protects your infrastructure from misuse or theft. If you are working on an application or a new device, your network security uses multiple layers of defence at the beginning and the end of your system. These layers block malicious attacks and prevent threats. Examples of network security practices include installing firewalls, implementing Network segmentation, and using a VPN to access secure data.

Data Security 

Data security relies on your ability to protect your digital data from misuse and corruption. Data security tools use technologies like encryption, access control, and two-factor authentication. Techniques like data encryption rely on changing readable information into an unreadable format for non-authorised people. For example, your WhatsApp chat messages are encrypted. Therefore, only you and the person you are talking to can read your messages right away. 

End Point Security 

How many devices do you use to access your work apps and tools? Many of us use at least two devices to follow up on work: our mobiles and our laptops. Our devices are endpoints for work, and they need to be secured from all breaches. That’s where end-point security comes from. End-point security practices include installing antiviruses on all your devices, strengthening and increasing device passwords, and constantly implementing new software updates on your endpoints to cover any security holes. 

Types of Cyber Attacks

A cyber attack is an attack initiated by a third party towards an entity or an organisation with the aim of controlling data, hindering communication, and causing losses. Overall, there are five common types of cyber attacks: 

Ransomware

A ransomware is a program a hacker uses to kick the data owner out of his system, encrypt the data, and demand money to release it back to the owner. A famous example of a ransomware attack is the 2022 Costa Rica ransomware attack. The attack targeted many government institutions forcing the government to shut its systems to avoid a leak of the database of millions of citizens. Costa Rica lost 30 million dollars per day just from that attack. 

DoS 

The most well-known attack is the Blizzard Entertainment DoS ( Denial of service) attack. It was an  attack that exhausted the game's systems enough to shut it down. DoS attacks usually start after the attacker takes control of multiple systems and computers that the company owns. He then starts exhausting the system with fake data, forcing it to shut down and forcing the company to spend millions just to get its systems back up again. 

Phishing

Have you ever had an email that looked authentic; however, upon checking the sender’s email, you found an extra E added to a domain that you know very well? That is how a phishing attack starts. A hacker who wishes to get your data usually sends you an enticing email with an offer you would love. Unknowingly, you would click on the link inside the email, enter your data and wait for an offer or an order that was never placed. Now the hacker has your data and you could lose money from a credit card or your data could be used in another crime. 

MITM Attack 

An MITM attack, also known as a Man-in-the-Middle Attack, is a well-known technique in which a hacker who wishes to track the communications between his target and multiple other people positions himself in the middle. This attack, commonly seen in movies and dramas, allows criminals to blackmail their victims or steal company secrets undetected.

Password Attacks

The most common password attacks use decryptors to figure out individuals' passwords. Before OTPs and 2-factor authentications were invented, password attacks were a real risk; however, the percentage of these attacks has diminished year after year.

How to Develop a Cyber Security Strategy?

To protect your company from cyber attacks, you have to adopt a proactive cyber security strategy by setting up a team or outsourcing a cyber security agency to help you identify vulnerabilities, mitigate risks, and implement top security measures. 

Steps for a Successful Cyber Security Strategy

Build Awareness

The first step for any organisation is to set up regular security training for its employees to avoid human errors that could result in a phishing attack or even ransomware. 

Identify Security Vulnerabilities 

Vetting your tools and identifying holes in your apps or systems should be a top priority in your strategy. You should also set a plan to identify external systems your team uses and their risks. 

Mitigate Risks 

If an attack occurs, you must ensure you have the right tools to stop that attack as quickly as possible without losing data or money. You can do so by  running different scenarios with the help of multiple teams to mitigate risks of an attack.

Additionally, many companies offer Bug Bounties as an extra step to mitigate possible attacks. Bug bounties are basically bounties that are given by major companies to an outsider who reports a bug to the company. Using these bounties, companies list the help of outsiders as well as their teams to find bugs and report them. 

Define roles and responsibilities.

If you intend to build a cyber security team within your company, defining the responsibilities of each security team member should always be a main part of your strategy. Cyber security jobs include titles like 

1. A security analyst: a person who analyses and identifies holes 
2. A security engineer: a person who builds security solutions to cover up security holes. 
3. A team leader: the person responsible for communications, planning and setting priorities.

Cyber Security Services

If instead of setting an in-house team, you decide to hire  a consultant agency with experience in the field. A firm can offer you multiple services that would set you on the right track and help you track your cyber security strategy. Top services include 

Penetration Testing 

A consulting firm can run penetration testing to simulate an attack on your system and identify holes. These tests usually try to attack your servers using internal, external, and targeted testing. 

Internal testing helps identify system vulnerability while external testing using an ethical hacker helps identify hidden bugs and miscalculations. Additionally, targeted testing is done on certain systems or apps previously identified as weak. 

Vulnerability Testing 

Vulnerability testing helps identify if a system is vulnerable to known cyber security risks by assigning severity levels to different risks and recommending mitigation tactics according to severity and importance. 

Threat Intelligence 

Threat intelligence tests help identify the most important data that needs to be preserved under different levels of security. Analysing your data is the core of threat intelligence as it helps prevent data loss and helps you identify the correct safety guidelines for your data portals.

Frequently Asked Questions

What are the benefits of cyber security?

Cyber security enhances productivity as employees don’t fear their efforts will be stolen by a stranger at any minute. Additionally, small companies impacted by cyber-attacks lose a lot of money, which could result in layoffs to continue the business. Some businesses have even closed their doors after a cyber attack; therefore, cyber security ensures business continuity. Finally, cyber security helps businesses gain new customers as your customers will not fear that their data will land in the wrong hands at any time. 

Who is leading the world in cyber security?

The US has maintained its leading position in cyber security for years. As the home of the top cyber security companies and the country with the highest cyber security budget, the country has always set basic cyber security standards for the world to follow.
