Security and privacy over the internet have always been one of the main concerns for individual users and organizations. Every year the internet community is plagued by malware and phishing attacks resulting billions of dollars lost. It is very important to know what cyber security stands for and what are its implications.
What is Cyber Security?
Every practice, exercise, and technology used to protect networks, data, programs, software, and computer from cyber-attacks, breaches, and unauthorized access comes under the purview of cyber security.
How do Cyber Security Attacks Occur?
The fundamentals of cyber-attacks revolve around the vulnerabilities present in a company’s security. As per our experts, there are three security aspects one should take care of.
Issues in network, software and device design- Attackers often see through the errors in the design of the company’s security system. You must take care of the patch management to regularly update the software and applications.
Features- sometimes, attackers use the software elements used to improve customer experience to decipher the system.
User error – The most well-designed security software can be easily cracked due to user error. Thus, employees have to be trained to identify and take appropriate actions in the situation of a cyber breach.
You must also know the types of cyber security attacks prevalent today. They are listed as follows:
Malware includes any software that is developed to damage and corrupt a network, computer or a device with nasty intentions. It contains dangerous software which can potentially harm your system. These programs are designed in a way that they cannot be detected easily by users as well as detection mechanisms.
You must be shocked to know that both small and large organizations are at a continuous risk of getting hit by malware. These attacks have only increased in recent years, and every system upgrade gets hacked after a point of time.
Some commonly used malware are described as follows:
Viruses – This type of malware duplicates itself within a system to the limit where it corrupts the entire data.
Trojan Horses – Such malware cover their real identity in the form of useful application and destroy the system before stealing valuable information.
Worms – Unlike viruses, worms tend to spread vicious codes in a system after replicating itself. They use a system’s bandwidth to send original codes to the computer and also delete important files or send them out through email.
Rootkits – It is a group of software that doesn’t allow a user to know that their system is corrupted. Even anti-virus software is unable to track them as they showcase themselves as useful files. They affect the system before it even starts thus becoming hard to discover.
Backdoors or Trapdoors – A backdoor created by a programmer for troubleshooting or personal reasons can be used by an attacker to enter, destroy and burglarize the system.
Being the most used method to corrupt a system, phishing is mostly a targeted method of deceiving a system. The cyber attackers try to cheat employees in revealing their passwords and other confidential information to a third party through websites, emails, and messaging services.
Thus, this method does not hack the system but manipulates its owner to undertake actions as said by the attacker. More than often, emails are used to send such messages at a large scale to addresses cracked from retail websites. These attackers use various techniques to dupe a person via man-in-the-middle attacks, revived corporate sites and keyloggers.
Typically, these emails include sophisticated information to fool the smartest people in providing their account details and passwords. Moreover, these emails also contain links that can quickly introduce spyware, malware, and Trojans in the user’s device.
Common types of Phishing apart from email threats include:
Spear Phishing- As the name suggests the fake emails are targeted towards a specific organization or user.
Keyloggers and screen loggers – In such a method, the attackers gain access to a user’s keyboard to know their passwords and other information.
Men in the middle phishing (MITM) – Attackers position themselves between a client and an organization to record their communication. Eventually, they get the password or the required information and leave the discussion without a hint of their existence.
Hence, you must take care of cybersecurity at any moment your system can get corrupted. It is better to stay safe than regret afterward.
