What is Cybersecurity?
Cybersecurity is the process and techniques involved in protecting sensitive data, computer systems, networks, and software applications from cyberattacks. The cyberattacks are general terminology that covers many topics, and some popular are:
- Tampering systems and data stored within
- Exploitation of resources
- Unauthorized access to the targeted system and accessing sensitive information
- Disrupting the normal functioning of the business and its processes
- Using ransomware attacks to encrypt data and extort money from victims
The attacks are now becoming more innovative and sophisticated, which can disrupt the security and hacking systems. So it’s very challenging for every business and security analyst to overcome this challenge and fight back with these attacks.
To understand the need for Cybersecurity measures and their practices, let’s take a quick look at the types of threats and attacks.
Ransomware
Ransomware is a file encryption software program that uses a unique, robust encryption algorithm to encrypt the files on the target system. The authors of the Ransomware threat generate a unique decryption key for each of its victims and save it on a remote server. Thus, users cannot access their files by any application.
The ransomware authors take advantage of this and demand a considerable ransom amount from the victims to provide the decryption code or decrypt the data. But such attacks have no guarantee of recovery of data even after paying the ransom.
Botnets Attacks
Botnets were initially designed to carry out specific tasks within a group. It is defined as a network or group of devices connected with the same network to execute a task. But this is now being used by bad actors and hackers that attempt to access the network and inject any malicious code or malware to disrupt its working. Some botnet attacks include:
- Distributed Denial of Service (DDoS) attacks
- Spreading spam emails
- Stealing of confidential data
Botnets attacks are generally carried out against large-scale businesses and organizations due to their huge data access. Through this attack, the hackers can control many devices and compromise them for their evil motives.
Social Engineering Attacks
Social engineering is now a common tactic used by cybercriminals to gather user’s sensitive information. It may trick you by displaying attractive advertisements, prizes, huge offers, and asking you to feed your personal and bank account details. All the information you enter there is cloned and used for financial fraud, identity fraud, and so.
It is worth saying about the ZEUS virus that is active since 2007 and is being used as a social engineering attack method to steal the victims’ banking details. Along with financial losses, Social engineering attacks can download other destructive threats to the concerned system.
Cryptocurrency Hijacking
Cryptocurrency hijacking is the new addition to this cyber world. As digital currency and mining are becoming popular, so it is among cybercriminals. They have found their evil benefit to cryptocurrency mining, which involves complex computing to mine virtual currency like Bitcoin, Ethereum, Monero, Litecoin, etc.
Cryptocurrency investors and traders are the soft targets for this attack.
Cryptocurrency hijacking is also known as “Cryptojacking”. It is a program designed to inject mining codes silently into the system. Thus, the hacker silently uses the CPU, GPU, and power resources of the attacked system to mine for the cryptocurrency.
Phishing
Phishing is a fraudulent action of sending spam emails by imitating to be from any legitimate source. Such mails have a strong subject line with attachments like an invoice, job offers, big offers from reputable shipping services, or any important mail from higher officials of the company.
The phishing scam attacks are the most common cyberattacks that aim to steal sensitive data like login credentials, credit card numbers, bank account information, etc. To avoid this, you should learn more about phishing email campaigns and their preventive measures. One can also use email filtering technologies to avoid this attack.
Malware
Malware is a broad term referring to all malicious programs that can harm a computer system or network. It includes viruses, worms, ransomware, spyware, and trojanware that can steal data, corrupt files, disrupt operations, or even take control of a system with malicious intent.
Supply Chain Attacks
Supply chain attacks target less-protected third-party vendors or suppliers of a company to gain access to that company’s network. This attack leverages the trust between business partners, and hence, it is difficult to defend.
Zero-day Attacks
These attacks exploit vulnerabilities in software that the software vendor is unaware of. Since no patch exists to fix the vulnerability, these attacks are highly effective and can cause significant damage before a solution is developed. Zero-day attacks are often used by sophisticated attackers targeting high-value targets like government agencies or critical infrastructure.
DDoS Attacks
DDoS attacks overwhelm a website or network with a flood of traffic, making it unavailable to legitimate users. Hackers get control of a network of compromised computers, which bombards the target with junk requests to achieve this attack. These disrupt online services, causing financial losses and reputational damage.
IoT Attacks
IoT attacks target IoT-connected devices such as smart home appliances, wearables, or industrial control systems. Attackers can exploit insecure IoT devices to steal data, disrupt operations, or even launch further attacks on a wider network.
Trojanware
Trojanware is a type of malware disguised as legitimate software that tricks users into installing them. After installation, it gets unauthorized access to the system to easily steal data, disrupt system operations, or even install other malware.
Eavesdropping
Eavesdropping involves secretly listening to phone calls or intercepting e-communications, such as emails or DMs. Eavesdroppers use various techniques to capture confidential information that they utilize for identity theft or other fraudulent activities.
The key concept of Cybersecurity
Cybersecurity is a very broad term but is based on three fundamental concepts known as “The CIA Triad“.
It consists of Confidentiality, Integrity, and Availability. This model is designed to guide the organization with the policies of Cybersecurity in the realm of Information security.
Confidentiality
It defines the rules that limit access to information. Confidentiality takes on the measures to restrict sensitive information from being accessed by cyberattackers and hackers.
In an organization, people are allowed or denied access to information according to its category by authorizing the right persons in a department. They are also given proper training about the sharing of information and securing their accounts with strong passwords.
They can change the way data is handled within an organization to ensure data protection. There are various ways to ensure confidentiality, like two-factor authentication, data encryption, data classification, biometric verification, and security tokens.
Integrity
This assures that the data is consistent, accurate, and trustworthy over its period. It means that the data within the transit should not be changed, altered, deleted, or illegally being accessed.
Proper measures should be taken in an organization to ensure its safety. File permissions and user access control are the measures controlling the data breach. Furthermore, tools and technologies should be implemented to detect any change or a breach in the data. Various organizations use a checksum and even cryptographic checksum to verify the integrity of data.
To cope with data loss or accidental deletion, or even cyberattacks, regular backups should be there. Cloud backups are now the most trusted solution for this.
Availability
Availability in terms of all necessary components like hardware, software, networks, devices, and security equipment should be maintained and upgraded. This will ensure the smooth functioning and access of Data without any disruption. Also, providing constant communication between the components through providing enough bandwidth.
It also involves opting for extra security equipment in case of any disaster or bottlenecks. Utilities like firewalls, disaster recovery plans, proxy servers, and a proper backup solution should ensure to cope with DoS and DDoS attacks.
What is Vulnerability Management?

How Does Cybersecurity Protect Against Cyber Threats?
Cybersecurity utilizes a multi-layered approach that involves both prevention and response strategies. This continuous process requires constant vigilance and adaptation to stay one step ahead of evolving threats.
Preventing Cyber Threats
To proactively ensure security, cybersecurity implements the following cybersecurity controls:
- Intrusion Detection/Prevention Systems (IDS/IPS) and Firewalls: These filter inbound and outbound traffic for suspicious activity. Firewalls block unauthorized access attempts, while IDS/IPS can raise alerts or even block threats automatically by detailed monitoring.
- Antivirus and Anti-Malware Software: Antivirus and Anti-Malware Software applications proactively scan systems for viruses, worms, malware, spyware, and trojans to quarantine or remove them before infection.
- Encryption: Encryption is a sophisticated method to scramble data and turn it into an unintelligible format. It safeguards sensitive information both while in transit and at rest.
- Strong Passwords: A strong password policy that emphasizes complex combinations of characters makes it harder for hackers to gain access, even if they breach the outer defenses.
- Access Controls: Limiting access to systems and data based on user permissions effectively prevents cyber threats. Multi-factor authentication (MFA) adds another layer of security beyond a password by requiring additional verification steps.
- Security Awareness Training: Educating employees about cybersecurity best practices, like identifying phishing emails and avoiding suspicious links, is crucial for preventing cybercrime. This works as the first line of defense against social engineering attacks.
Mitigating and Addressing Threats
Below are outlined steps to prevent and address security threats.
- Security Information and Event Management (SIEM): SIEM collects security data from various sources to offer a centralized view of security events. Thus, users can initially identify suspicious activities and potential breaches.
- Incident Response Plans: The plan for responding to a cyberattack is critical. This plan outlines threat containment, damage mitigation, and system restoration steps.
- Vulnerability Management: Vulnerability Management approach includes regularly applying security updates with the latest security fixes. It allows users to close exploitable gaps.
- Threat Intelligence: Another proactive defense mechanism is staying informed about the latest cyber threats and attack methods.
- Digital Forensics and Incident Recovery: After a cyberattack, the digital forensics team investigates the incident and collects evidence to determine the scope of the breach. Incident recovery focuses on restoring affected systems and data as early as possible.
Example of Cybersecurity Measures for Cyber Threat: Phishing Email
Below is an example of the cybersecurity measure for the cyber threat.
Cybersecurity Protection
- Email Filtering: Preventive measures like email filtering can block suspicious emails. As it uses sender reputation, keywords, and attachment types to screen incoming emails, less number of emails with phishing attempts reach the inbox.
- User Training: Organizations can educate and train employees to raise awareness about phishing attempts. Thus, they can easily identify phishing attempts by red flags, such as misspelled URLs, requests for personal information, generic greetings, and urgency tactics.
Cybersecurity Response
- Investigation by IT Security: IT security teams should investigate suspicious emails following the due procedure. The investigation includes email header analysis, sender legitimacy verification, and screening of malicious links or attachments.
- Threat Isolation: When a phishing email bypasses filters and compromises a user account, the IT security team can quickly restrict access to sensitive data and systems to isolate the threat.
- Securing Compromised Accounts: The IT team must immediately disable the compromised accounts to prevent further damage. They should take other measures like password reset, adding a strong and unique password, scanning user devices for malware, and recovering from data breaches.
What Are Technologies Used in Cybersecurity?
Cybersecurity relies on a diverse range of technologies to defend against ever-evolving threats.
