A cyber security threat is an attempt by an individual or group to obtain access to a network, alter data, or steal confidential information.
Cyber-attacks and data breaches do not spare any firm. Some cyberattacks are capable of destroying computer systems.
As cyber threats get more complex, your company must install security safeguards to protect its data.
What are the Top Security Threats?
To begin, you must understand the distinction between compass and cyber security and the types of dangers you will face virtually every day – both current information security threats and new and emerging threats that will afflict your organization tomorrow.
Malware
The most common cyberattack is malicious software, more commonly known as malware. Malware includes spyware, ransomware, backdoors, trojans, viruses, and worms.
Spyware software allows attackers to obtain information about your computer activities by transmitting data covertly from your hard drive.
Ransomware is designed to encrypt files on a device, rendering any files (and the systems that rely on them) unusable. Usually, malicious actors demand a cash ransom in exchange for decryption.
A backdoor circumvents routine authentication procedures to access a system. This gives the attacker remote access to resources within an application, such as databases and file servers, and allows malicious actors to issue system commands and update malware remotely.
Trojans are malware or code that acts as a legitimate application or file to trick you into loading and executing the malware on your device. A trojan’s goal is to damage or steal your organization’s data or harm your network.
A computer virus is malicious code designed to spread from device to device. These self-copying threats are usually intended to damage a machine or steal data.
Worms are malware that distributes copies of themselves from computer to computer without human interaction and do not need to attach themselves to a software program to cause damage.
Malware is usually installed into the system when the user opens a malicious link or email. Once installed, malware can block access to critical components of your network, damage your system, and export confidential information to destinations unknown.
Your organization can prevent malware-based cyber security attacks by
Use reputable antivirus and anti-malware solutions, email spam filters, and endpoint security solutions to ensure that your cyber security updates and patches are all up to date.
They require your employees to undergo regular cyber security awareness training to teach them how to avoid suspicious websites and to avoid engaging with suspicious emails—limiting user access and application privileges.
Phishing and Spear Phishing
Phishing is a type of social engineering in which consumers are duped into providing sensitive information such as usernames and passwords, bank account information, Social Security numbers, and credit card information.
Hackers typically send phishing emails that appear to come from reputable sources such as PayPal, eBay, financial institutions, or friends and coworkers. The fraudulent communications attempt to trick users into clicking on links in the emails, which route them to fraudulent websites requesting personal information or installing malware on their devices.
Opening attachments in phishing emails can also install malware or allow hackers to manage your devices remotely. Spear phishing is a more sophisticated type of phishing assault in which cybercriminals only target privileged people such as system administrators and C-level executives. Attackers may utilize information from a person’s social media accounts to appear more legitimate to the target.
Smishing, vishing, clone phishing, domain spoofing, URL phishing, watering hole phishing, and evil twin phishing are all phishing. All of this can be very expensive.
Organizations can take numerous steps to lower the likelihood of phishing:
- Implement cyber security awareness training for every employee.
- Highlight the importance of phishing reporting.
- Run random phishing simulations.
- To create secure, encrypted connections, push HTTPS on your website.
- Institute access management policies and procedures.
- Use reliable email and spam filters.
- Two-factor authentication.
- Use email encryption and email signing certificates.
Man-in-the-Middle (MITM) Attacks
These attacks occur when malicious actors insert themselves into the middle of a two-party communication. Once the attacker intercepts the incoming message, they filter and steal sensitive information and then return different responses to the original user.
Sometimes malicious actors set up fake wi-fi networks or install malware on users’ computers or networks. Also called eavesdropping attacks, MITM attacks aim to gain access to your business or customer data.
