Cyber security is the set of tools and practices used to protect computers, mobile devices, servers, electronic systems, networks, and data from attacks, breaches, malware, viruses, and other threats. These threats can be anything from a hacker stealing personal information to ransomware that encrypts files and demands payment in exchange for decryption.
The field of cybersecurity is constantly changing and evolving. As a result, cyber security professionals need to have a wide range of skills, including technical expertise, critical thinking, communication, networking, and teamwork. Luckily, there are many ways to get started in cybersecurity. Whether you want to get certified or just take the first step, you can use resources like podcasts, blogs, forums, and Capture-the-Flag (CTF) competitions to gain the skills you need to land your first job in this growing career.
The importance of cyber security is highlighted by the sheer number of breaches and data thefts that occur every year. These incidents can have far-reaching consequences for businesses, ranging from damage to reputation to lost revenue. In the United States, for example, the 2014 JPMorgan Chase breach exposed the names, addresses, phone numbers, and account information of 76 million households. While certain sectors are more appealing to cybercriminals than others — such as medical services and retailers — all businesses have the potential to fall victim to hackers.
As a result, all companies should invest in cyber security measures. This includes keeping software up to date and using a firewall. It also means implementing two-factor authentication and being wary of phishing scams. Backing up data is crucial, too, as it can help reduce the impact of a breach or virus.
