“Cyber-Security is a shared responsibility, and it boils down to this: in Cyber-Security the more systems we secure, the more secure we all are” ~ Jeh Johnson
Cyber security is becoming the fundamental part of the world today. Our national security and economic buoyancy depend on a sound and resilient cyberspace. How we can protect our network, systems, and data from cyber-attacks are all included in cyber security. With cyber security, illegal exploitations to organizations and individuals can both be avoided, leading to a better and protected world of technology. Although there is no guarantee that we are free from any spyware, we can take some actions to lower the risk of being hacked.
Many organizations today are searching for a reliable base or a plan to tackle the cyber attackers. With such an arrangement they can prevent cyber-attacks from happening, beforehand. All the information systems must unite and work together as one to achieve this podium.
Cyber security involves:
- Network security
- End-user education
- Application security
- Information security
- Operational security
- Disaster recovery/ Business continuity planning
Some reasons cause the toil in protecting the cyberspace, for example, linkages among cyberspace and physical systems, the difficulty of lowering vulnerabilities, and outcomes in the sophisticated cyber networks. Also due to the skill of hostile players who operate from anywhere in the world. The cyber threat to censorious infrastructure operations increasingly subjected to sophisticated cyber intrusions that pose new perils. There also increased the risk for wide-scale or high-upshot events that could cause derange or harm our services on which our economy and daily lives of millions of people depend, due to the information technology which merged with physical infrastructure operations.
Today, we are more interconnected than ever. This increasing connectivity among us with all its pros poses some cons as well. The risks of frauds, abuse, and thefts grow. We become vulnerable to cyber-attacks such as spear phishing, social media fraud, and corporate security breaches, as we become more reliant on the modern technology. If we want to safeguard the cyberspace, supportive law enforcement capabilities and cyber security are our essentials, to begin with. If we take an example in the United States, there exists Department of Homeland Security (DHS) working with other federal agencies over there to conduct high-impact criminal investigations to beat cyber criminals.
This compartment incorporates services to guard the usability, integrity, safety, and reliability of the network. A vast array of threats are targeted and prevented from entering or spreading through the channels via a secure network security program. Network security constitutes:
- Virtual Private Network (VPNs), which provide secure remote access to our web traffic from prying eyes by staying anonymously online
- Anti-spyware and anti-virus
- Intrusion prevention systems (IPS) which recognize fast-expanding threats like zero-hour or zero-day attacks
- Firewall, which allows or blocks unauthorized access to your networks by security rules and it is the first system of network security.
DNS Spoofing is a sort of computer attack in which a user is forced to navigate to a hoax website which looks like a real one. The purpose of this is to reroute traffic or steal credentials of the users. These attacks can go on for an extended period without being discerned and can cause significant cyber security issues. DNS spoofing achieved by substituting the IP addresses stored in the DNS server with the ones under the authority of the attacker. After it completed, the user gets directed to the sham websites placed by the attackers, whenever they try to go to a particular site. To avoid this inconvenience, you can update your DNS server and sustain separated servers for internal and public services and use secure keys to sign updates received from other DNS servers.
Hackers can assume for highly qualified and brilliant in computers. Breaking a security system requires more proficiency than actually creating one. Pirates, in general, computer parlance, are called White hats, grey hats, and black hats. Inquisitive people have only some computer language skills to sanction them to hack a system to locate prospective loopholes in the network security system are the grey hats. Some hackers hack to take control over the system for personal gains which are termed as the black hats and the other hack to check their security systems to make it more hack-proof, they termed as white hats. To conclude, in this era of technology and more interconnections than before, we share more information with each other which we should protect the cyber spaces.
