Just as global warming is the biggest threat to our environment, cybersecurity is the number one enemy of a peaceful digital environment. Be it large corporations or individuals, no one is safe from cyberattacks.
According to a study conducted by the University of Maryland, an American citizen becomes a victim of cyberattacks every 39 seconds.
That said, it is more alarming how sophisticated cybercriminals have become and threaten us with cyberattacks like never before. For instance, a seemingly harmless ad on a website may also be a type of cyberattack.
However, cybersecurity measures may be quite effective in preventing, blocking, or eliminating cyberattacks. And below, I’m going to explain everything there is need to know about cybersecurity.
So, whether you’re a freelancer, run a small business, or simply scroll social media, read on to find out how you can stay safe from cyberattacks.
What is Cybersecurity?
Essentially, cybersecurity measures can be tools, such as applications or software, technologies, policies, and practices to secure our devices and data stored on them.
As I said above, cyberattacks have become so advanced now that most people may not even realize that they’re under attack. For instance, a malware inside an ad may be installed on your device as soon as you watch or click on the ad.
Besides these malicious ads called malvertisements, social engineering attacks, phishing, ransomware, malware, and other cyberattacks may also discreetly steal your sensitive data.
At an individual level, cybercriminals attack people’s devices or networks to access their data. They can steal sensitive information, like bank account details, photos, contacts, social accounts passwords, and more.
At the corporate level, cybercriminals attack companies, intending to gain unauthorized access to their database. Then, they sell the stolen information or use it for other malicious purposes.
However, to prevent and mitigate the impact of these attacks, cybersecurity measures can be implemented. That said, it’s best to rely on multiple cybersecurity measures as they can help significantly enhance the protection of your device and data against cyberattacks.
While I’ll discuss more about what cybersecurity measures you can take, first, let’s discuss why cybersecurity is crucial in today’s digital world.
Why is Cybersecurity Important?
It’s a common practice for most people to store sensitive information on their smartphones, laptops, etc. Similarly, companies collect and save crucial information such as financial data, customer details, and more on their servers.
Hence, it’s vital to have solid cybersecurity measures in place to stop cyberattacks. Below are a few more reasons that explain why cybersecurity is important:
- Effective cybersecurity measures help minimize or eliminate the threat of data breaches.
- Companies can secure their sensitive database with solid cybersecurity measures.
- Cybersecurity measures can help companies avoid unnecessary disruptions and delays caused by cyberattacks.
- Customers’ trust in a business may solidify when solid cybersecurity measures are in place.
Types of Cybersecurity:
Moving forward, I’ll explain some major types of cybersecurity below.
Mobile Security
Our smartphones store crucial data such as passwords, social media accounts, contacts, emails, and more. And to prevent this data from falling into the hands of a few bad actors, mobile security may help. Specifically, Mobile Application Management (MAM) and Enterprise Mobility Management (EMM) are two major ways of securing our data on smartphones.
Information Security
Encryptions, access controls, data loss preventions, and other means that help secure our data confidentiality and integrity, fall under information security. In case of any cyberattack, information security can greatly reduce the chances of data leakages.
Network Security
These measures are generally more helpful for corporations where a large network of computers or connected devices exists. Tools and software such as intrusion detection systems, firewalls, or VPNs are some of the common types of network security.
Endpoint Security
Even though endpoint security has multiple purposes, its major responsibility is to prevent any unauthorized access or data breaches initiated by bad actors. The endpoint security measures include antivirus software and intrusion prevention systems to block any unauthorized access in our devices.
Cloud Security
This cybersecurity type is mostly used by corporations where cloud computing or applications are heavily involved in day-to-day operations. The purpose of cloud security is to secure the connection between the cloud and the connected devices to prevent any unauthorized access or data leakage.
Types of Cybersecurity Threats
Before moving on to the best cybersecurity practices, I believe it’s important to understand how cybercriminals attack our devices and data. Below, I have explained some of the most common types of cybersecurity threats.
Malware
Malware stands for “malicious software,” and it’s an umbrella term for several types of viruses. The purpose of malware is to simply steal, corrupt, or delete the information stored on a device. Here are some of the most common types of malware:
- Ransomware – Bad actors steal or hack users’ data for a heavy ransom.
- Spyware – Cybercriminals install malware on users’ devices to steal data without their knowledge.
- Trojans – These are disguised as legitimate tools/software that people may install on their devices. Once downloaded, it steals or corrupts users’ data.
- Cryptojacking – Hackers may use users’ computing power to mine cryptocurrencies.
Phishing
Cybercriminals take help from SMS and emails or create fake social media profiles and trick people into revealing sensitive information. Here are some types of phishing attacks:
- Vishing – Bad actors pretend to call users from reputable institutions and ask for personal information.
- Whaling – Cybercriminals usually attack senior citizens and steal their sensitive information, such as insurance data, to gain financial benefits.
- Spear Phishing – Here, the goal of bad actors is to gain login credentials of sensitive apps such as social media or bank accounts.
Spoofing
In this type of cyberattack, the hackers portray themselves as a credible source to gain people’s trust and then lure them into revealing sensitive information. Here are some common types of spoofing attacks:
- Address Resolution Protocol (ARP) Spoofing – In ARP spoofing, users may unknowingly send crucial data to bad actors instead of sending it to the original host of that information.
- Domain Spoofing – Cybercriminals may create fake credentials, such as websites, emails, contacts, names, and more, to target people.
- Email Spoofing – Bad actors may create fake business credentials, such as emails, and target a company’s executives to reveal sensitive information.
Best Cybersecurity Practices:
Now, let’s take a look at cybersecurity measures that can help you prevent and mitigate cyberattacks.
Use a Secure Internet Connection
Be it spammy emails or installing malware, most cybercriminals use the internet to conduct cyberattacks. However, you can avoid cyberattacks if your internet connection is secured with advanced security protocols.
Recently, I was researching about secured internet service providers (ISPs) and found Xfinity Internet. Upon further research, I came to know that Xfinity offers an xFi Gateway with advanced security features, such as warning users about visiting suspicious websites.
Not just this, but xFi Gateway also blocks remote access to your devices from malicious sources.
Use Strong Passwords
Strong and complex passwords alone may not be able to counter a cybersecurity threat. However, they may help enhance your devices or apps’ security and create hurdles for novice hackers, who may not be able to crack them.
Setting up a strong password is easier, as you should always use a combination of upper and lower-case alphabets, along with numeric and special characters.
Use Virtual Private Network and Firewall
Although it is not necessary to use a Virtual Private Network (VPN) and firewall together, I believe using them simultaneously may be more effective in countering cyberattacks.
Essentially, when you connect to a VPN, it creates an encrypted tunnel between your device and its server. So, all the incoming and outgoing data from your device goes through the encrypted tunnel first, and then to its intended destination.
Plus, a VPN also alters your device’s IP address and assigns it a fake one. In such cases, cybercriminals may fail to install any malware on your device, since it would be unrecognizable.
On the other hand, a firewall can actively identify and block malicious threats that may try to harm your device. So, I believe using a VPN and a firewall simultaneously may offer better protection against cyberattacks.
Do Not Open Emails from Unknown Senders
One of the best, yet most ignored cybersecurity practices is to never open an email from an unknown sender. As I mentioned above, cybercriminals may impersonate a trusted source to connect to their targets. And, most times, they take help from emails and send malicious links or attachments.
Plus, if someone asks you to reveal sensitive information over a call or SMS, do not trust them.
It is most likely that cybercriminals would be impersonating a trusted source to extract and exploit your sensitive information.
