Security breach or data breach?
The terms security breach and data breach are sometimes used interchangeably, but they’re two different things. It’s usually a question of order. A security breach happens first. A data breach may follow. One exception: A company may negligently expose data. That’s considered a data breach.
A security breach occurs when an unauthorized party bypasses security measures to reach protected areas of a system. A security breach can put the intruder within reach of valuable information — company accounts, intellectual property, the personal information of customers that might include names, addresses, Social Security numbers, and credit card information.
If a cybercriminal steals confidential information, a data breach has occurred. Personally identifiable information is often sold on the dark web and can be used to commit crimes such as identity theft.

What is a NOC, and How It Improves Data Center Availability
On the off chance that your organization is dealing with numerous systems, you are most likely mindful of the challenges associated with observing them at the same time. Be that as it may, ideally, you know about the significance of this, also. Your information and your customers' information is private, and your systems should be fully operational immediately. Except if you have an in-house group that can deal with this degree of system the board, you might need to consider re-appropriated technical support. NOC professionals and designers assume on the liability of observing foundation wellbeing, security, and limit. With the entirety of this data, they can settle on educated choices and alter the frameworks to streamline your system execution and authoritative profitability. When there is an issue, they convey cautions, in light of the seriousness, type, and level of aptitude expected to determine it, and any of the classes that you and your NOC group indicate. When you settle the issue, changes are made to the framework and the observing framework, with the goal that issues don't repeat.
Far off IT INFRASTRUCTURE MANAGEMENT AND MONITORING CAN INCLUDE VARIOUS IT TOOLS. HERE ARE SOME OF THE SERVICES YOU SHOULD LOOK INTO:
Antivirus and Anti-malware: Don't be a survivor of these infections, worms, and different malevolent programming's that need to erase documents, get to individual information and utilize your PC to assault different systems in your office. Your NOC group will suggest the product that you ought to use, just as do all the examining, investigating, and settling any found issues. This ought to likewise incorporate a firewall and interruption avoidance framework for observing and the board.
Reinforcement on all equipment: Having multi reinforcements, including a cloud reinforcement can forestall disastrous accidents in your office.

Why Network Security Assessment for Business
Because of the sheer size of the internet and the many security issues and vulnerabilities that have been published, opportunistic attackers will continue to scour the public IP address space for vulnerable hosts. The combination of new vulnerabilities exposed daily and IPv6 adoption allow opportunistic attackers to always compromise a certain percentage of Internet networks.
Classification of Internet-Based Attackers
At a high level, Internet-based attackers can be divided into two groups:
Opportunistic attackers scan large Internet address spaces for vulnerable systems
Concentrated attackers who attack specific Internet-based systems with a specific target in mind
Opportunistic threats involve attackers using persistent, automated rooting tools and scripts to compromise vulnerable systems on the Internet. Public Internet researchers have found that after deploying a vulnerable, basic-ready server setup, it is typically compromised within an hour by automated software running in this way.
Most Internet hosts compromised by opportunistic attackers are unsecured home user systems. These systems then turn into zombies running software, logging user keystrokes, launching denial of service (DoS) flood attacks, and acting as a platform to attack and compromise other systems and networks.
Concentrated attackers take a more complex and systematic approach with a clear goal in mind. A focused attacker thoroughly probes each entry point into the target network, port scans each IP address, and thoroughly evaluates each network service. This resolute attacker knows his weakness, even if he cannot compromise the target network on the first attempt. Having detailed knowledge of the site's operating system and network services could allow an attacker to release new attack scripts in the future to compromise the network.
The most at-risk networks are those with a large number of public hosts. Having many entry points in the network increases the potential for compromise and as the network grows, risk management becomes increasingly difficult. This is commonly known as the defender's dilemma. Defenders must ensure the integrity of each entry point, whereas attackers only need access from one point to be successful.
Assessment Service Description
Security vendors offer a variety of assessment services that are branded in different ways. Figure 1-1 shows key service offerings with in-depth assessments and relative costs. Each type of service can provide different levels of security assurance.
Various security testing services
Figure 1-1. Various security testing services
Vulnerability scans use automated systems (eg Nessus, ISS Internet Scanner, QualysGuard or eEye Retina) with minimal hands-on proficiency and vulnerability assessment. This is an inexpensive way to ensure that obvious vulnerabilities are not discovered, but it does not provide a clear strategy for improving security.
Network security assessment is an effective combination of automated and real manual vulnerability testing and validation. Reports are often hand-written, accurate and concise, providing practical advice that can improve your company's security.
Web application testing includes post-authentication evaluation of web application components, command injection, and identification of weak privileges and other weaknesses in specific web applications. Testing at this level involves extensive manual competencies and consultant engagement and cannot be easily automated.
Complete penetration testing is beyond the scope of this book. It contains multiple attack vectors (such as phone combat calls, social engineering, and wireless testing) to damage the target environment. Instead, this book fully describes and explains the methodology employed by Internet-based attackers to remotely compromise IP networks. This can improve IP network security.
On-site inspections provide the clearest picture of network security. Advisor has local system access and execution tools that can identify everything undesirable on each system, including rootkits, weak user passwords, insufficient privileges, and other issues. 802.11 wireless testing is typically performed as part of an on-site audit. Field inspections are also outside the scope of this book.

WHY IS IT IMPORTANT FOR MY COMPANY TO USE A NETWORK OPERATIONS CENTER (NOC)

Types of security breaches
There are a number of security breaches, depending on how access to the system was obtained:
The abuse attacks a system vulnerability, such as an outdated operating system. For example, legacy systems that have not been updated in businesses using outdated and no longer supported versions of Microsoft Windows are particularly vulnerable to exploits.
Weak passwords can be cracked or guessed. Even now, some people are still using the 'password' password and 'pa $$ word' is not much more secure.
Malware attacks such as phishing emails can be used to gain login. Just one employee needs to click a link in a phishing email for malware to start spreading on the network.
Car downloads use viruses or malware that are compromised or sent via a fake website.
Social engineering can also be used to gain access. For example, an intruder calls an employee who claims to be from the company's IT help desk and asks for a password to 'fix' the computer.
In the breach examples we mentioned above, a number of different techniques were used to gain access to networks - Yahoo was attacked by a phishing attack, while Facebook was hacked by an exploit.
security breach examples
We're talking about security breaches as they affect large organizations, the same security breaches apply to individuals' computers and other devices. You are probably less likely to be attacked using an exploit, but many computer users have been infected with malware, whether it was downloaded as part of a software package or introduced to the computer through a phishing attack. Weak passwords and the use of public Wi-Fi networks can compromise internet communications.
