Types of security breaches

 

There are a number of types of security breaches depending on how access has been gained to the system:

security breach meaning

An exploit attacks a system vulnerability, such as an out of date operating system. Legacy systems which haven't been updated, for instance, in businesses where outdated and versions of Microsoft Windows that are no longer supported are being used, are particularly vulnerable to exploits.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 entry. It only takes one employee to click on a link in a phishing email to allow malicious software to start spreading throughout the network.

Drive-by downloads use viruses or malware delivered through a compromised or spoofed website.

Social engineering can also be used to gain access. For instance, an intruder phones an employee claiming to be from the company's IT helpdesk and asks for the password in order to 'fix' the computer.

In the security breach examples we mentioned above, a number of different techniques were used to gain access to networks — Yahoo suffered a phishing attack, while Facebook was hacked by an exploit.

Though we've been talking about security breaches as they affect major organizations, the same security breaches apply to individuals' computers and other devices. You're probably less likely to be hacked using an exploit, but many computer users have been affected by malware, whether downloaded as part of a software package or introduced to the computer via a phishing attack. Weak passwords and use of public Wi-Fi networks can lead to internet communications being compromised.

What are the basic types of firewalls?

Learn the basics of different types of firewalls, the differences between them, and how each type protects your network in different ways.

different types of firewalls

A firewall is a basic but necessary layer of security that acts as a barrier between your private network and the outside world. From first-generation stateless firewalls to next-generation firewalls, firewall architectures have evolved tremendously over the past 40 years. Organizations today can choose from a variety of firewall types, including application-level gateways (proxy firewalls), stateful firewalls, and circuit-level gateways, and can even use multiple types simultaneously for in-depth and comprehensive security solutions.

What is a firewall and what is it used for?

A firewall-type firewall is a security tool that monitors inbound and/or outbound network traffic to detect and block malicious data packets according to predefined rules, allowing only legitimate traffic to enter a private network. Implemented as hardware, software, or both, a firewall is often the first line of defense against malware, viruses, and attackers trying to break into an organization's internal networks and systems.

Much like a metal detector entrance at the front door of a building, a physical or hardware firewall inspects every data packet before it enters. It checks source and destination addresses and checks data packets according to predefined rules. must pass. When data packets are on an organization's intranet, software firewalls can further filter traffic, allowing or blocking access to specific ports and applications on computer systems, providing better control and security against insider threats.

Access Control Lists can identify certain untrusted IP (Internet Protocol) addresses. The firewall will drop all data packets from that IP. Alternatively, you can specify trusted source IPs in your access control list and the firewall will only allow traffic from the listed IPs. There are several ways to set up a firewall. The extent of security you provide often depends on the type of firewall and how it is configured.

What is Managed service delivery model

IT managers are under constant pressure to reduce costs while meeting operational expectations, security requirements, and performance improvement requirements. To solve this problem, they have a managed service provider, also known as an MSP, which they call a managed service delivery model.

MSPs take a holistic approach to IT services and offer a much higher standard than most organizations can achieve in-house. In addition, best-in-class providers provide customers with ongoing maintenance and management of their existing infrastructure and service with end-user support.

Why do you need it?

Today's IT managers are under tremendous pressure to keep costs low while meeting their business' performance, operational expectations and security requirements. Most financial experts recommend moving to predictable cost models such as managed services in these circumstances. Companies that provide these services are called Managed Service Providers (MSPs). The best time to meet with your MSP is when you set strategic goals for the future or deploy new services in your IT environment. In many cases, company employees may not have experience with new technologies or be unable to maintain new services or applications. Hiring contractors to provide services is more expensive when budgets are stagnant or tight and can provide less value in supporting a company's ever-growing performance goals. This generally applies equally to small businesses and large businesses.

The managed service model has evolved significantly over time and experienced providers have perfected their offerings. It is very effective for businesses such as:

Rely on your IT infrastructure to adequately support your daily business operations.

We do not have enough trained personnel or time to formally carry out proper maintenance, upgrades and repairs.

To provide a high level of service to your business, you want to pay a flat monthly fee for the service.

For most business services, IT supports the business engine. From software to hardware and the technology needed to keep services running, companies can invest significant capital to build and maintain in-house support staff. However, given the maturity of the managed services model and the transition to virtualization and the cloud, the need for onsite IT staff may be limited to exceptions where operational sensitivity is justified. To better predict IT costs amid uncertain requirements, companies may consider leveraging managed services specialists.

MSPs often price their services on a subscription-based model. Depending on the service you choose, pricing is usually based on the number of units priced for the different package categories. Some provide on-site customer support as needed. Basic services often start out as monitoring services that identify potential problems that you can fix yourself. At the other end of the spectrum, service providers offer comprehensive managed services that cover everything from alerts to troubleshooting.

What is a Security Breach?

 

In cybersecurity, a security breach refers to a successful attempt by an attacker to gain unauthorized access to an organization's computer systems. Outages can include stealing sensitive data, corrupting or sabotaging data or IT systems, or actions aimed at falsifying websites or damaging reputations.

security breach meaning

Security breaches and the law

Security breaches have legal significance. Laws in some countries may expose organizations to fines or other penalties if they are violated and certain sensitive data is affected. The European Union's General Data Protection Regulation (GDPR) defines a personal data breach as "a breach of security that results in accidental or unlawful destruction, loss, alteration, unauthorized disclosure or access to personally identifiable information (PII)". The U.S. Health Insurance Portability and Accountability Act (HIPAA) defines a security breach as “an unauthorized use or disclosure…” that compromises the security or privacy of protected health information.

Security breach vs data breach

A security breach is a general term that refers to any breach of corporate systems. A data breach is a specific event in which data is maliciously accessed, stolen or destroyed.

Security breach vs security incident

A security event, such as a security breach, represents an attacker's attempt to access or damage corporate systems. The difference is that most security incidents do not result in an actual breach.

For example, a brute-force attack against a protected system attempting to guess multiple usernames and passwords is a security event, but cannot be identified as a breach unless the attacker manages to guess a password.

A security incident can qualify as a security breach if it allows an attacker to access protected systems. If the attacker gained access to sensitive data, it is a data breach.

How To Optimize a (SOC) Security Operations Model

Although incident management monopolizes much of the SOC's resources, the RSSI (Director of Information Security) is responsible for the overall risk and compliance overview. To connect operational and data silos between these functions, an effective strategy requires an adaptive security architecture that enables organizations to implement enhanced security operations. This approach increases efficiency through integration, automation, and orchestration and reduces the amount of work hours required, improving your information security management posture.

noc vs soc

An optimized security operations model requires the adoption of a security framework that facilitates the integration of security solutions and threat intelligence into daily processes. SOC tools, such as centralized, actionable dashboards, help integrate threat data into dashboards and security monitoring reports to keep operations and event and activity management informed. By linking threat management with other risk and compliance management systems, SOC teams can better manage their overall risk posture. These configurations support continuous visibility across systems and domains and can use exploitable intelligence to improve the accuracy and consistency of security operations. Centralized functions reduce the burden of manual data exchange, auditing and reporting.

Operational threat management must begin with a careful assessment. In addition to defenses, an organization must assess processes and policies. Where is the strong organization? What are the gaps? What is the risky posture? What data is collected and how much of this data is used?

Although every organization is different, some basic resources and best practices in security operations today are getting the attention they need. A reasonable threat management process begins with a plan and includes discovery (including basic calculation to promote detection, normalization and correlation of anomalies), screening (based on risk and asset value) , analysis (including contextualization) and scope (including iterative research) Threat management processes feed into priority and characterized cases in incident response programs. A well-defined response plan is absolutely essential to contain a threat or minimize the damage caused by a data breach.

Figure 1. Threat management plans integrate and structure many processes in IT security and operations.

Effective visibility and threat management will depend on many data sources, but it can be difficult to classify useful and timely information. The most valuable data proved to be event data produced by countermeasures and IT assets, indicators of commitment (IoC) produced internally (through malware analysis) and externally (through the threat intelligence stream) and available system data from sensors (eg host, network, database, etc.).

These data sources are not just an entry in threat management. They add context and make information valuable and actionable for more accurate, precise and rapid assessment in all interactive and interactive threat management efforts. Accessing and effectively using the right data to support plans and procedures is a measure of organizational maturity. A "mature" scenario would include a workflow that conveys the correct information or allows direct action through operational consoles and products. This flow integrates IT operations and security tools and equipment to respond to incidents in the event of a critical event.

All of these assessments will help prioritize where increased investment or reduced friction is needed to ensure that threat management implementation meets objectives. Consultants and penetration testing can help assess organizational maturity and strategy and verify security response against attacks to get a current measure of an organization's ability to detect and contain malicious events . Compared to similar companies, this review examined can help justify and explain the need to redirect or invest in the resources of cybersecurity operations.

Importance of Network Security Assessment

Security Risk Assessment Methodology

Most basic risk assessments follow the same general steps.

network security assessment

1. Create a resource list

What is your company's most valuable asset? Before testing for vulnerabilities, organizations should reconsider the networks, devices, data, and other assets they want to protect. As part of this step, you should document your entire IT infrastructure. This will give you a full map of your network, so if you get hacked, you can quickly find the attacker.

2. Assess the vulnerability of your assets

Once you know what your assets are, you can start investigating to find vulnerabilities. Threats can come from anywhere outside your organization, internally with poor security practices, or from third parties with poor security practices and accessing your network. Risks can vary widely, so the assessment should be comprehensive. A good rating should include:

Thorough scan of all ports and other vectors on the network

Assess your inner weaknesses

Discover Wi-Fi, Internet of Things and other wireless networks

Review third-party access to networks and assets

Review policies for employee behavior such as bringing fraudulent devices or opening suspicious emails.

3. Defense test

At this point, some organizations can aggressively test their defenses by running penetration testing to see if an attacker can easily compromise their assets. Assessment is important to identify risks, but penetration testing shows how easy it is to compromise your network.

4. Weakness Support

At this point, you may have noticed some weaknesses in your network. Create a list of vulnerabilities and develop a remediation plan.

5. Continuous security monitoring

The most comprehensive and best network risk security assessments don't keep your assets safe forever. As threats and technologies constantly change, so does risk, so it is important to continuously monitor and review the risk landscape so that organizations can respond quickly and efficiently to new attacks or threats.

How can SecurityScorecard help?

Risk management is difficult without seeing a complete picture of an organization's vulnerabilities. This is why network security assessment is so important. It will help you develop an IT infrastructure map that shows where all your vulnerabilities are.

To keep this map up to date on a daily basis, it is important to invest in smart tools that scan your infrastructure for vulnerabilities. SecurityScorecard, for example, allows you to easily monitor your entire organization's security risk, providing a tailored view of your overall footprint.

Our custom scorecards provide portfolio cybersecurity risk monitoring, remediation and documentation, enabling organizations to protect their systems, networks, software and data.

Custom scorecards allow organizations to gain more insight into how different lines of business affect their safety scores. It also provides suggestions to help you solve the problem of lowering your security score, so you can always keep your network safe.

Three types of security walls

 

Firewalls are used to prevent unauthorized access by third parties on a private network. These are network security systems (hardware/software based) that monitor and control the flow of traffic between the Internet and a private network according to a set of user-defined rules. Firewalls protect your organization's computer network from unauthorized inbound or outbound access and provide optimal network security.

There are three basic types of firewalls that companies use to protect their data and devices, blocking destructive elements from their networks. Packet filter, health check and proxy server firewall. We will briefly introduce each of them.

different types of firewalls

packet filter

Packet filter firewalls control network access by analyzing outgoing and incoming packets. Allows packets to traverse or block paths against a predetermined criterion, such as allowed IP addresses, packet types, and port numbers, such as: Packet filtering techniques are suitable for small networks, but they become complex when applied to large networks. These firewalls cannot block all kinds of attacks. The application layer cannot exploit vulnerabilities or overcome attacks that fight fraudulent attacks.

status check

Stateful Packet Inspection (SPI), also known as dynamic packet filtering, is a powerful firewall architecture that inspects end-to-end traffic flows. These smart and fast firewalls use smart methods to block unauthorized traffic by analyzing packet headers, providing proxy services and inspecting packet state. These firewalls operate at the network layer of the OSI model and are more secure than basic packet filtering firewalls.

Proxy server firewall

A proxy server firewall, also known as an application-level gateway, is the most secure type of firewall that effectively protects network resources by filtering messages at the application layer. Proxy firewall masks IP addresses and restricts traffic types. They provide a complete protocol-aware security analysis of the protocols they support. A proxy server provides the best internet experience and improves network performance.

This is about a basic firewall configured to protect private networks. Whatever firewall you choose, make sure to check the proper configuration as loopholes can do more harm than good without a firewall. Create a secure network and install appropriate firewalls to restrict access to computers and networks.
