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; 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.
What is cybersecurity all about?
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 defense 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.
People
Users must understand and comply with basic data security principles like choosing strong passwords, being wary of attachments in email, and backing up data. Learn more about basic cybersecurity principles.
Processes
Organizations must have a framework for how they deal with both attempted and successful cyber attacks. One well-respected framework can guide you. It explains how you can identify attacks, protect systems, detect and respond to threats, and recover from successful attacks. Watch a video explanation of the NIST cybersecurity framework (1:54)
Technology
Technology is essential to giving organizations and individuals the computer security tools needed to protect themselves from cyber attacks. Three main entities must be protected: endpoint devices like computers, smart devices, and routers; networks; and the cloud. Common technology used to protect these entities include next-generation firewalls, DNS filtering, malware protection, antivirus software, and email security solutions.
Why is cybersecurity important?
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.
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.
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.
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.
Cisco and the NIST Cybersecurity Framework
National Institute of Standards and Technology, or NIST for short an innovative new cybersecurity framework – one that’s easy to understand, one that helps organizations prioritize and cost-effectively tackle cyber risks, one that provides a common language to discuss cybersecurity, and one that references existing best practices from around the globe
It’s the NIST Cybersecurity Framework, or CSF for short. As today’s cyber threats continue to grow in volume and sophistication — without enough cyber experts to go around — it’s more important than ever to have a simple and solid way to bring cyber risks down to an acceptable level. That’s what the CSF brings to the table. And it’s gaining momentum: In this infographic NIST cites Gartner research that says 30% of US organizations already use the CSF — a number that’ll grow 50% by 2020.
So how does Cisco tie into this? Well, as an experienced IT company with thousands of employees worldwide, some might wonder whether there are any new or innovative ideas here either. Hey, we have news for you: Today’s Cisco is the clear cybersecurity leader. Did you hear that SC Magazine awarded us with the Best Security Company and Best Security Organization Awards this year?
Firewalls and Next Generation Firewalls (NGFW)
NGFW is a part of 3rd generation of firewall technology, combining a traditional firewall with other network device filtering functionalities, such as an application firewall using in-line deep packet inspection (DPI), an intrusion prevention system (IPS). Other techniques might also be employed, such as TLS/SSL encrypted traffic inspection, website filtering, QoS/bandwidth management, antivirus inspection and third-party identity management integration (i.e. LDAP, RADIUS, Active Directory).
Firewalls are a standard security tool for the majority of companies, but in today’s changing threat landscape, next generation firewalls are the only firewalls that can provide proper protection.
Next-generation firewall vs. traditional firewall
NGFWs include the typical functions of traditional firewalls such as packet filtering,[2] network- and port-address translation (NAT), stateful inspection, and virtual private network (VPN) support. The goal of next-generation firewalls is to include more layers of the OSI model, improving filtering of network traffic that is dependent on the packet contents.
