Definition of cybersecurity
Cybersecurity is defined as taking steps to protect servers, computers, electronic systems, mobile devices, networks, and online data from cyber-criminals and malicious attacks. It is also referred to as electronic information security or information technology security.
Different Categories of Cybersecurity
The term cybersecurity can apply in different contexts. Below are a few common categories cybersecurity can be divided into:
1. Application security
This is the practice of keeping devices and software free of cyber threats. A hacked mobile app could leak data and information meant to be private. To successfully secure an application, developers must start from the design stage before the app is deployed.
2. Network security
This is the practice of keeping a computer network secure from intruders either from devious malware or targeted assaults.
3. Information security
This is the practice of protecting the privacy and integrity of data and information both in transit and storage.
4. Operational security
This is the process of securing and supervising information assets. The decisions and measures that regulate where and how data will be stored and shared fall under this category. The permissions that are given to users when accessing this information also falls here.
5. End-user education
This procedure aims to address the most impulsive and unpredictable aspect of cybersecurity- humans. Anyone in your office could introduce a computer virus accidentally into the system by not following security measures and practices put in place. Through end-user education, users are educated on following cyber-security procedures such as deleting a suspicious email attachment and avoiding unknown websites. These lessons are essential for the online security of any business.
Cybersecurity safety tips
Below are ways individuals and companies can protect themselves against cyber threats:
- Always update your operating system and software to benefit from added security features.
- Use strong passcodes and passwords that cannot be easily guessed.
- Use anti-virus to perceive and get rid of security threats.
- Don’t open attachments in emails if you don’t know the sender; it could infect your computer with a virus.
- Don’t click on any URL links in emails from unknown senders. This is a popular way of launching a cyber-attack.
- Don’t use public WiFis; they leave you susceptible to cyber-attacks.
The measure of cyber threats
With increased numbers of breaches annually, cyber threats continues to evolve rapidly across the world. Government organizations, retailers, and medical organizations have experienced the most attacks from malicious cyber-criminals. Most of these entities are attractive to hackers because they collect medical and financial information. However, organizations in other sectors can also be targeted for corporate spying, customer attacks, and client data.
With an increase in cyber threats, the International Data Corporation forecasts that the total expenditure on cybersecurity solutions will increase by up to 133.7 billion dollars by 2022. Many governments worldwide are taking steps to protect their citizens from rising threats by helping companies implement good online practices. The National Institute of Standards Technology developed a cyber-security framework for the US to fight the spread of computer viruses and help detect an attack as it is happening.
