In today’s world we can see that humans are so much dependent to technology. Everyone is evolving with time. Today everyone is using smart phones, computers and laptop. So this all leads to cyber crimes. Cyber crimes have risen immensely since last few years. So to fight against them cyber security is the solution.
Cyber Security
Cybersecurity is the practice of protecting systems, networks, and programs from digital attacks. These cyberattacks are usually aimed at accessing, changing, or destroying sensitive information; extorting money from users via ransomware; or interrupting normal business processes. Implementing effective cybersecurity measures is particularly challenging today because there are more devices than people, and attackers are becoming more innovative. A successful cybersecurity approach has multiple layers of protection spread across the computers, networks, programs, or data that one intends to keep safe. In an organization, the people, processes, and technology must all complement one another to create an effective defence from cyber attacks. A unified threat management system can automate integrations across select Cisco Security products and accelerate key security operations functions: detection, investigation, and remediation.
Users
Users should be very well aware of the cyber crimes. They should take all the required measures to fight against it. They can have unique passwords, being wary of attachments in email, and backing up data. They should know basic data security principles. People often ignore all these measures and ends being victim of cyber crimes.
Types of cybersecurity threats
- Phishing
Phishing is the practice of sending fraudulent emails that resemble emails from reputable sources. The aim is to steal sensitive data like credit card numbers and login information. It’s the most common type of cyber attack. You can help protect yourself through education or a technology solution that filters malicious emails.
- Social engineering
Social engineering is a tactic that adversaries use to trick you into revealing sensitive information. They can solicit a monetary payment or gain access to your confidential data. Social engineering can be combined with any of the threats listed above to make you more likely to click on links, download malware, or trust a malicious source.
- Ransomware
Ransomware is a type of malicious software. It is designed to extort money by blocking access to files or the computer system until the ransom is paid. Paying the ransom does not guarantee that the files will be recovered or the system restored.
- Malware
Malware is a type of software designed to gain unauthorized access or to cause damage to a computer.
Cyber Security Technologies and Tools
- Firewalls
A firewall is a network security device that monitors incoming and outgoing network traffic and decides whether to allow or block specific traffic based on a defined set of security rules. Firewalls have been a first line of defence in network security for over 25 years. They establish a barrier between secured and controlled internal networks that can be trusted and untrusted outside networks, such as the Internet.
- Encryption
The process of converting data into a format that can only be read or accessed with the correct encryption key.
- Intrusion Detection Systems (IDS) and Intrusion Prevention Systems (IPS)
Systems that monitor network traffic for suspicious activity and take action to prevent unauthorized access.
- Security Information and Event Management (SIEM) Systems
Systems that collect, analyse, and manage security event data from various sources to detect and respond to security threats.
Emerging Trends in Cybersecurity
- Artificial Intelligence (AI) and Machine Learning
AI and machine learning technologies are being used to enhance cybersecurity defenses by detecting and responding to threats in real-time.
- Internet of Things (IoT) Security
With the proliferation of IoT devices, securing these connected devices and networks against cyber threats has become a top priority.
- Zero Trust Security
The zero trust security model assumes that no entity, whether inside or outside the network, should be trusted by default, and requires strict identity verification for all users and devices.
- Cloud Security
As organizations increasingly migrate their data and applications to the cloud, ensuring the security of cloud-based environments has become critical.
Importance of Cyber Security
In today’s connected world, everyone benefits from advanced cyberdefense programs. At an individual level, a cybersecurity attack can result in everything from identity theft, to extortion attempts, to the loss of important data like family photos. Everyone relies on critical infrastructure like power plants, hospitals, and financial service companies. Securing these and other organizations is essential to keeping our society functioning.
Everyone also benefits from the work of cyberthreat researchers, like the team of 250 threat researchers at Talos, who investigate new and emerging threats and cyber attack strategies. They reveal new vulnerabilities, educate the public on the importance of cybersecurity, and strengthen open source tools. Their work makes the Internet safer for everyone.
