CYBER SECURITY & CYBER SECURITY

Cyber Security is a serious issue for all verticals, today sharing informative insight on cybersecurity original link. Organizations face many threats to their information systems and data. Understanding all the basic elements of cybersecurity is the first step to meeting those threats.

Cybersecurity is the practice of ensuring the integrity, confidentiality and availability (ICA) of information. It represents the ability to defend against and recover from accidents like hard drive failures or power outages, and from attacks by adversaries. The latter includes everyone from script kiddies to hackers and criminal groups capable of executing advanced persistent threats (APTs), and they pose serious threats to the enterprise. Business continuity and disaster recovery planning are every bit as critical to cybersecurity as application and network security. Security should be top of mind across the enterprise, and come with a mandate from senior management.

Security training

The human is always the weakest element in any cybersecurity program. Training developers to code securely, training operations staff to prioritize a strong security posture, training end users to spot phishing emails and social engineering attacks — cyber security begins with awareness.

All companies will experience some kind of cyber attack, even if strong controls are in place. An attacker will always exploit the weakest link, and many attacks are easily preventable by performing basic security tasks, sometimes referred to as “cyber hygiene.” A surgeon would never enter an operating room without washing their hands first. Likewise, an enterprise has a duty to perform the basic elements of cyber security care such as maintaining strong authentication practices and not storing sensitive data where it is openly accessible.

A good cyber security strategy needs to go beyond these basics, though. Sophisticated hackers can circumvent most defenses, and the attack surface — the number of ways or “vectors” an attacker can gain entry to a system — is expanding for most companies. For example, the information and the physical world are merging, and criminals and nation-state spies now threaten the ICA of cyber-physical systems such as cars, power plants, medical devices, even your IoT fridge. Similarly, the trends toward cloud computing, bring your own device (BYOD) policies in the workplace, and the burgeoning internet of things (IoT) create new challenges. Defending these systems has never been more important.

Types of cybersecurity

The scope of cybersecurity is broad. The core areas are described below, and any good cybersecurity strategy should take them all into account.

Critical infrastructure

Critical infrastructure includes the cyber-physical systems that society relies on, including the electricity grid, water purification, traffic lights and hospitals. Plugging a power plant into the internet, for example, makes it vulnerable to cyber attacks. The solution for organizations responsible for critical infrastructure is to perform due diligence to protect understand the vulnerabilities and protect against them. Everyone else should evaluate how an attack on critical infrastructure they depend on might affect them and then develop a contingency plan.

Network security

Network security guards against unauthorized intrusion as well as malicious insiders. Ensuring network security often requires trade-offs. For example, access controls such as extra logins might be necessary but slow down productivity.

Tools used to monitor network security generate a lot of data — so much that valid alerts are often missed. To help better manage network security monitoring, security teams are increasingly using machine learning to flag abnormal traffic and alert to threats in real time.

Cloud security

The enterprise’s move into the cloud creates new security challenges. For example, 2017 has seen almost weekly data breaches from poorly configured cloud instances. Cloud providers are creating new security tools to help enterprise users better secure their data, but the bottom line remains: Moving to the cloud is not a panacea for performing due diligence when it comes to cyber security.

Application security

Application security (AppSec), especially web application security, has become the weakest technical point of attack, but few organizations adequately mitigate all the OWASP Top Ten web vulnerabilities. AppSec begins with secure coding practices and should be augmented by fuzzing and penetration testing.

Rapid application development and deployment to the cloud has seen the advent of DevOps as a new discipline. DevOps teams typically prioritize business needs over security, a focus that will likely change given the proliferation of threats.

Internet of things (IoT) security

IoT refers to a wide variety of critical and non-critical cyber-physical systems, like appliances, sensors, printers and security cameras. IoT devices frequently ship in an insecure state and offer little to no security patching, posing threats to not only their users, but also to others on the internet, as these devices often find themselves part of a botnet. This poses unique security challenges for both home users and society.

"CYBERCRIME IS THE GREATEST THREAT TO EVERY COMPANY IN THE WORLD"

Types of cyber threats

Common cyber threats fall under three general categories:

Attacks on confidentiality: Stealing, or rather copying, a target's personal information is how many cyber attacks begin, including garden-variety criminal attacks like credit card fraud, identity theft, or stealing bitcoin wallets. Nation-state spies make confidentiality attacks a major portion of their work, seeking to acquire confidential information for political, military, or economic gain.

Attacks on integrity: Also known by its common name, sabotage, integrity attacks seek to corrupt, damage, or destroy information or systems, and the people who rely on them. Integrity attacks can be subtle — a typo here, a bit fiddled there — or a slash and burn campaign of sabotage against a target. Perpetrators can range from script kiddies to nation-state attackers.

Attacks on availability: Preventing a target from accessing their data is most frequently seen today in the form of ransomware and denial-of-service attacks. Ransomware encrypts a target's data and demands a ransom to decrypt it. A denial-of-service attack, typically in the form of a distributed denial-of-service (DDoS) attack, floods a network resource with requests, making it unavailable.

The following describes the means by which these attacks are carried out.

Social engineering

Attackers aren't going to hack a computer if they can hack a human instead. Socially engineered malware, often used to deliver ransomware, is the No. 1 method of attack (not a buffer overflow, misconfiguration, or advanced exploit). An end-user is tricked into running a Trojan horse program, often from a website they trust and visit often. Ongoing user education is the best countermeasure against this attack.

Phishing attacks

Sometimes the best way to steal someone's password is to trick them into revealing it This accounts for the spectacular success of phishing. Even smart users, well-trained in security, can fall for a phishing attack. That's why the best defense is two-factor authentication (2FA) — a stolen password is worthless to an attacker without a second factor, such as hardware security token, or soft token authenticator app on the user's phone.

Unpatched software

It's hard to blame your enterprise if an attacker deploys a zero-day exploit against you, but failure to patch looks a lot like failure to perform due diligence. If months and years pass after disclosure of a vulnerability, and your enterprise has not applied that security patch, you open yourself to accusations of negligence. Patch, patch, patch.

Social media threats

Catfishing isn't just for the dating scene. Believable sock puppet accounts can worm their way through your LinkedIn network. If someone who knows 100 of your professional contacts strikes up a conversation about your work, are you going to think it strange? Loose lips sink ships. Expect social media espionage, of both the industrial and nation-state variety.

Advanced persistent threats

Speaking of nation-state adversaries, your enterprise has them. Don't be surprised if multiple APTs are playing hide-and-go-seek on your corporate network. If you're doing anything remotely interesting to someone, anywhere, you need to consider your security posture against sophisticated APTs. Nowhere is this truer than in the technology space, an industry rich with valuable intellectual property many criminals and nations will not scruple to steal.

2018 cybersecurity trends and predictions

The new year brings new challenges and opportunities in cybersecurity. Here are some predictions of developments in the New Year.

AI-powered attacks:

• Spam/fraud/phishing messaging utilizing chatbots.
• Smarter brute force attacks with AI-powered password guessing. 
• AI-powered attack obfuscation

McAfee Inc.’s recent threats predictions report identified five key cybersecurity trends to watch in 2018:

• An adversarial machine learning “arms race” between attackers and defenders
• Ransomware to evolve from traditional PC extortion to IoT, high net-worth users, and corporate disruption
• Serverless Apps to create attack opportunities targeting privileges, app dependencies, and data transfers
• Connected home devices to surrender consumer privacy to corporate marketers
• Consumer apps collection of children’s content to pose long-term reputation risk

It is hard to argue with these predictions, particularly those concerning an “arms race” and the evolution of ransomware.

SOME CYBER SECURITY TIPS

Cybersecurity careers

Executing a strong cybersecurity strategy requires you have the right people in place. The demand for professional cybersecurity folk has never been higher, from the C-suite down to the security engineers working on the front lines. Security leaders have elbowed their way into the C-suite and boardrooms, as protecting company data becomes mission critical for organizations. A chief security officer (CSO) or chief information security officer (CISO) is now a core management position that any serious organization must have.

Roles have also grown more specialized. The days of the generalist security analyst are fading fast. Today a penetration tester might focus on application security, or network security, or phishing users to test security awareness. The incident response may see you on call 24/7. The following roles are the foundation of any security team.

CISO/CSO

The CISO is a C-level management executive who oversees the operations of an organization’s IT security department and related staff. The CISO directs and manages strategy, operations, and the budget to protect an organization’s information assets.

Security analyst

Also referred to as cyber security analyst, data security analyst, information systems security analyst, or IT security analyst, this role typically has these responsibilities:

• Plan, implement and upgrade security measures and controls
• Protect digital files and information systems against unauthorized access, modification or destruction
• Maintain data and monitor security access
• Conduct internal and external security audits
• Manage network, intrusion detection and prevention systems
• Analyze security breaches to determine their root cause
• Define, implement and maintain corporate security policies
• Coordinate security plans with outside vendors

Security architect

A good information security architect straddles the business and technical worlds. While the role can vary in the details by industry, is that of a senior-level employee responsible to plan, analyze, design, configure, test, implement, maintain, and support an organization’s computer and network security infrastructure. This requires knowing the business with a comprehensive awareness of its technology and information needs.

Security engineer

The security engineer is on the front line of protecting a company's assets from threats. The job requires strong technical, organizational and communication skills. IT security engineer is a relatively new job title. Its focus is on quality control within the IT infrastructure. This includes designing, building, and defending scalable, secure, and robust systems; working on operational data center systems and networks; helping the organization understand advanced cyber threats, and helping to create strategies to protect those networks.
