Cyber threats for businesses
Cyber espionage is a type of cyber exploitation in which an attacker takes advantage of a user’s computer by executing a program without the user’s knowledge. The operation runs in the background without attracting attention, and Cyber-criminals capture sensitive information after gaining access to it.
Ransomware or malware attacks
Ransomware or malware attacks affect businesses in many ways. For example, the data of affected systems can be stolen, which could lead to the loss of intellectual property or trade secrets vital for business success, along with exposing sensitive information like customer records, etc.
Denial of service or DoS attacks
This type of attack aims to make an online service unavailable by flooding it with traffic from multiple sources, resulting in denying access to users who want to avail of its services. It’s one of the oldest forms of cyberattacks targeting businesses.
Advanced persistent threat (APT)
APTs are often used to steal intellectual property or trade secrets that can be sold illegally to competitors. They also aim at accessing sensitive information that could be exploited for monetary benefits by the attacker, who is usually backed up financially and technologically well-equipped, resulting in attacks being difficult for businesses to detect before it’s too late.
Business email compromise (BEC)
It’s another form of phishing attack that targets senior executives through BEC scams and spear-phishing emails aimed at staff who have high-level access to money or sensitive data.
Distributed denial-of-service attacks (DDoS)
A type of cyber attack where the malicious traffic comes from many hosts, which are usually infected with malware or compromised computer systems.
Data breaches caused by insider threats
Data breaches can be very dangerous for businesses because they involve employees, partners, or vendors who may have the necessary access to data, leading to the loss of intellectual property and customer information.
These are when attackers manage to get unauthorised access into company networks, where they often steal critical assets, including customer records and sensitive proprietary business information, among other things.

How can businesses implement cyber security?
There are several measures that companies can implement to ensure cyber security management. Businesses need to invest in a team of professionals who have the expertise and knowledge necessary to manage security risks, threats and vulnerabilities, along with implementing policies and procedures and controls that will help organisations be prepared against possible attacks.
The following list highlights some steps that can prove beneficial for businesses:
- Identifying vulnerabilities and threats proactively
- Implementing a firm security policy that covers all aspects of an organisation along with training staff to follow the same.
- Following cyber security architecture based roadmap to ensure systems are secure by design.
- Ensuring software, hardware, and network security systems are up-to-date on patches which helps in reducing risk exposure while also protecting against emerging viruses or cyber risks.
- Conducting internal audits to ensure processes are in place for compliance with regulatory requirements and industry best practices.
- Ensuring the system architecture has sufficient security controls so that critical information is protected against cyber-attacks by rogue employees or external hackers/threats etc.
Advantages of cyber security for Individuals
For individuals, it means safety from identity theft which has become more common in recent times, with online shopping becoming a standard for many due to convenience and affordability. With cyber security measures implemented at home, you are well guarded against fraudulent transactions or data loss through malware etc. Following are some advantages of cyber security for individuals:
- Protection from identity theft, financial loss, customer data loss or impacts on business operations
- Prevents unauthorised access to data or personal details and records like passwords etc.
- Helps businesses in various forms such as secure software development, information security arrangements around authentication and authorisation areas, reducing cybersecurity risks, DDOS attacks, and building an organisation’s cyber resilience.
- Helps in the secure transfer of money through various payment options without worrying about security breaches.
- It prevents data or information from falling into the wrong hands.
- Protects against online fraud and theft of passwords etc.
- Helps in safe transactions for selling/buying products like eBay, Craigslist etc.
- Secures your social media accounts with strong password protection without worrying about hacks, viruses etc.
- Prohibits loss of data from viruses or malicious code

Cyber threats to individuals
This is the most common cyber threat involving stealing identities, leading to financial losses or even compromised accounts.
These are when attackers send fake emails pretending to be someone you know and asking for information like passwords, account details etc. It’s one of the oldest types of social engineering attacks that continue to fool unsuspecting users.
This is the most common type of cyber attack, which involves hackers encrypting your data or locking it up until you pay a ransom to get them back.
Emails are often sent pretending to come from legitimate sources along with asking for personal information like credit card details, account passwords etc.
This includes viruses, spyware or any malware that can harm your device along with stealing personal information and infecting the system with ransomware, among other things.
Social engineering attacks
This can be a severe cyber threat for individuals where attackers can bypass physical security controls or contact you over the phone, chat or on social media pretending to be someone you know and asking for personal information like account passwords.
Malware or spyware infections
Such attacks occur when you download and install software on your device without knowing that it’s malware or spyware. This is often done to gain access to someone’s system and explore internal digital security measures before lateral movement and cybercrime activities such as internal infiltration.
Mobile threats for Android devices
These are threats include malicious apps, ransomware, and identity theft, along with other types of mobile hacking attacks which can happen to both Android phones as well as tablets.
How can individuals implement cyber security?
You, too, can take measures to protect yourself against cyber risks and attacks by following the below-mentioned steps:
• Always use strong passwords for accounts that include a combination of uppercase and lowercase letters, numbers and symbols.
• Avoid using the same password across multiple websites and accounts. If your password is compromised and used on other sites, you could face many problems.
• Avoid sharing private information such as bank details, passwords, etc., unless you are sure about the person. It is recommended to verify the contact details and identity of a person before sharing any information online.
• Ensure you have antivirus protection on your system that will prevent malware, viruses etc., from compromising data or stealing company credentials.
• Make use of closed-source networks such as at home, where there is less risk exposure compared to public WiFi hotspots that are unsecured, untrusted and hence pose a greater risk.
Is there any drawback of cyber security?
One of the critical issues with cyber security is that it is constantly changing. This means that businesses and individuals have to update their security measures to stay protected continually. Additionally, cybercrime is continuously on the rise, which means that companies and individuals are increasingly becoming targets.
