Data breaches continue to plague businesses across the globe. The recent Equifax breach has left millions of Americans without their personal information. What should companies do to prevent such incidents from happening?
Data breaches are becoming more common due to the rise of cloud computing. In addition, hackers are constantly looking for new ways to exploit vulnerabilities. This means that even large organizations are vulnerable to cyber-attacks.
Companies need to take steps to secure their data. They should also educate employees on cybersecurity risks and train them to identify suspicious emails or other communications. This article will help you understand data protection essentials for everyone, how it applies to your business, and how you can protect yourself against hacking attempts. You’ll learn how to use email filters, firewalls, encryption software, password policies, and other tools to securely handle sensitive content.
It’s time to increase your level of understanding when it comes to data security in this post. Let’s get started!
What Is Data Security All About?
In today’s world, we have a lot of digital information stored online. For example, social media posts, bank account details, e-mails, photos, documents, and many other files are sent through the internet. Hackers attempt to steal these valuable assets by intercepting our Internet traffic.
A hacker may be able to steal usernames, passwords, credit card numbers, or any sensitive information contained within an email. It doesn’t matter whether it’s one individual or a large organization that’s affected. Our entire society is at risk, especially those with weak passwords.
A thief could use stolen credentials to access a company’s network and obtain internal information about its operations like financial records, customer names, employee information, and intellectual property. These types of hacks not only impact individuals, but they can also cause major damage to the reputation of a company as well.
How Does Data Security Work?
Data security works by using different methods. There are two main categories: physical and technical. Physical methods include things like locks and key cards. Technical approaches include things like VPN connections.
Physical Methods
Locks – Locks are used to restrict unauthorized personnel from accessing certain areas. A typical lock consists of three parts: a cylinder, a latch mechanism, and a locking mechanism. When the bolt is turned to the locked position, the latch engages the door frame so that the door cannot open unless the bolt is released.
Key Cards – Key Cards allow authorized persons to enter a facility while restricting others from entering. An ID badge verifies identity. Personal identification numbers (PINs) are usually required to use a keycard system.
Firewalls – Firewalls limit access to specific services within an organization. If someone tries to access a website outside of the firewall perimeter, then the connection request is denied. The firewall restricts websites and applications that users don’t want to see.
Technical Methods
VPN – A virtual private network allows users to connect to a remote server. This method encrypts the user’s Internet traffic so that it’s protected from eavesdropping. The encrypted traffic is sent across a public network and then decrypted upon arrival.
Encryption Software – Encryption software scrambles messages before they’re transmitted over the Internet. Only people who know the secret keys can unscramble the message. This way, no one else will be able to read your e-mail or other communications.
Hardware Devices – Hardware devices such as smart cards, USB dongles, and biometrics are becoming increasingly popular ways of verifying identities. They provide secure storage for personal data and prevent unauthorized access.
How can I protect myself against hacking attacks?
There are several steps you can take to make yourself less vulnerable to cybercrime. Here are some tips:
- Use strong passwords – You should never reuse passwords. Strong passwords contain characters like capital letters, lowercase letters, numbers, punctuation marks, and special symbols. Make sure that your password isn’t easy for anyone to guess.
- Keep your computer up to date – Keeping your computer updated helps ensure that hackers won’t have access to new vulnerabilities in your operating system. If you’ve got Windows 10 installed on your device, you’ll get automatic updates through Windows Update. Mac OS users can check out Apple’s support page for instructions on how to install updates manually. Linux users will need to go online and follow their distribution instructions.
- Use anti-virus programs – Antivirus software scans files and programs for viruses, spyware, adware, worms, Trojans, and other malware. It also blocks malicious links and websites that are trying to infect your computer with harmful content. Malicious content may appear when you’re viewing emails or surfing the Web. Many anti-virus products come bundled with parental controls, which help keep children safe.
- Back up your data – Backing up your data means creating copies of all your important information. You should back up at least once per week. One good option is to store your backups offsite. That way, if anything happens to your computer, all your data will still be safe and accessible via the cloud.
- Update your browser – Most browsers offer built-in virus protection. However, any time you open an unfamiliar link, you risk downloading something dangerous. For example, using Google Chrome, you can click on unknown links by pressing Ctrl + Shift + Del. To confirm whether a site is safe, hover over the lock icon in the address bar. If it says “Secure,” the site is okay. If it says “Not Secure,” then proceed with caution.
- Be careful about where you download apps – While there are a lot of free apps available, many times the app developer doesn’t pay attention to safety measures. Sometimes, apps contain hidden malware that steals your identity and data. When you download an app, always do a cursory scan to see what kind of permissions the app needs. Also, look for privacy policies and terms of service agreements before you agree to them.
- Protect your mobile device from attack – Your smartphone, tablet, or laptop contains sensitive data, including banking credentials and private conversations. Never share these details with strangers. Instead, use two-factor authentication (2FA) whenever possible. 2FA requires additional verification methods, such as a six-digit code sent to your phone or email account, in addition to your normal login credentials.
If you think you might be infected, you can try to remove the infection manually. First, make sure you’re running antivirus software and scanning for threats regularly. Then, run an antimalware program to determine exactly what’s causing the problems. Next, delete the offending files or folders. Finally, restart your computer so everything gets loaded again.
Final advice
There’s no single thing you can do to stop infections. But taking precautions like those above will help prevent most attacks. Always perform regular scans and updates for your devices. Keep your device locked down, only allowing trusted people to connect to it. Protect your financial data, don’t allow strangers to use your phone number, and never give anyone your password.
