Computers, especially ones connected to a network can never be 100% safe. New vulnerabilities and exploits are being discovered every day and cyber security professionals are in a seemingly never ending race with hackers and other malicious threats that attempt to compromise computers. However, there are many actions we can take in order to make a computer as safe as possible. Some of the main components of a safe computer include encryption, firewalls, and physical security. Encryption is very important when it comes to computer security and information integrity. For example, if passwords on the system are not encrypted or hashed and end up being stolen, it can lead to the system being compromised by attackers. Additionally, other sensitive information possibly belonging to customers needs the same level of security in order to make sure you maintain confidentiality of the data you possess. Since hackers are getting more advanced and computers are getting faster, you need to ensure that you are using the latest and best encryption method so that the method you’re using is actually effective. There are many encryption methods and you can choose the one that fits your environment the best depending on your needs such as speed and usability. Having firewalls that block malicious traffic is also important in order to secure your computer. This stops hackers from downloading sensitive files and uploading malicious software from your computer. Physical security is just as important as the other components. This is because if an attacker is able to steal the computer or inject a usb with a malicious program on it then it is highly likely that the data on it will be compromised. This is why preventative measures like security personnel and barriers should be onsite and employees should be wary of potential tailgates and shoulder surfers.
