What is cybersecurity?

Cybersecurity is how individuals and organizations guard against a cyber-attack. Cybersecurity’s primary function is to protect the devices that people use, such as smartphones, laptops and computers, and services we access from damage or theft. It is about stopping unauthorized access to our personal information on these devices and online.

Electronic devices play a significant role in modern life. We use them for online banking and shopping and email and social media. Cybersecurity can prevent cyber criminals from getting access to our data, accounts and devices.

An effective cybersecurity method has many layers of protection. In an organization, individuals, processes and technology must all correlate to successfully defend against cyber-attacks.

Online master’s degree

Baylor University offers an online master’s in computer science for non-CS majors. The curriculum includes technical expertise, innovative thinking, ethics and trends in technology across the world. Students are prepared to work in high-demand roles in software engineering and data science.

Critical infrastructure

Cybersecurity works to give continuity to the activity and services provided to inhabitants. The critical infrastructure consists of assets or systems essential for producing vital social and economic functions: security, food, health, energy, transport, financial services, information systems, etc. Damage to critical infrastructure through cybercrime could have a serious negative impact on society.

Present-day cybercriminals look for weaknesses in critical infrastructure systems to find information, take control of activities or organizations, or freeze or end activities. Security and protection have become crucial in a complex, interconnected, constantly evolving climate.

The proper functioning of the critical infrastructure continues beyond the organizations involved. Many essential functions need the support of a wide range of stakeholders, such as software companies, internet providers and regulators. Security strategies depend on all of these stakeholders working together.

All organizations should be using E2EE (end-to-end encryption), a procedure of communication security that stops third parties from accessing data when it is transmitted from one device or system to another. This should include a range of technologies and services, such as disaster recovery, cyber recovery, secure cloud architecture, privacy protection, data protection, and more.

Advances in digital technology have made the threat to critical infrastructure more common and potentially more dangerous. Industry and academic experts are used to protect cybersecurity capability. Defense and intelligence organizations provide information on impending threats and hazards so that suitable action can be taken.

Application security

Application security is creating, adding and testing security features within applications to avoid security vulnerabilities such as unauthorized access and interference.

Applications are frequently accessible across networks and connected to the cloud, increasing security threats’ and breaches’ vulnerability. Network-level security and application-level testing are required.

Application security types comprise authentication, authorization, encryption, logging and application security testing. Authentication procedures include the user providing a username and password when logging in. Multi-factor authentication requires more information from the user, such as an additional password or text message with a code. Once the user is authenticated, they can access and use the application. The system matches the user’s identity to an authorized user list. When the user is operating the application, other security precautions protect data from being accessed by cybercriminals.

In cloud-based applications, data can be encrypted during transmission. If a security breach occurs, logging can assist in identifying who accessed the data and how. Application log files give a time-stamped record of who entered the application and where it was accessed. Security testing is a process to check that all security controls function correctly.

Network security

Network security is the technology that protects a company’s infrastructure by stopping the entry of potential threats. Network security consists of tools that protect the network and the applications that run over it. Security will have many lines of defense that can be expanded and automated.

Many business applications are moving to private and public clouds, challenging network security. With cyberattacks increasing, the protection of network transmissions and infrastructure is critical.

Network security is pivotal to an organization’s ability to deliver customer products and services. It enables businesses to advance and protects the organization’s reputation.

The security architecture that implements network security consists of two main categories: access control and threat control. Access control restricts the movement of cyber threat actors throughout the network. Threat control works on traffic that has already entered the system to prevent damage from being done to the network. Threat control starts with the firewall and load balancer. An intrusion system is used to counterattack threats traveling through the network. Sandbox technologies capture unknown malware traveling through the system and traffic analysis catches oddities that may represent a threat.

Cloud security

The cloud refers to servers that are connected over the internet and the databases and software that run on those servers.

Cloud security is the technology to protect data within a cloud architecture. It ensures data privacy and compliance for data stored in the cloud.

Private clouds, public clouds and hybrid clouds are being used more, along with multiple public clouds using a multi-cloud strategy. The distribution and nature of cloud computing require a unique approach to data security.

Cloud security has controls that strengthen the system, caution against possible attackers, and detect incidents that have occurred. A business continuity plan and data backup plan can be in place in case of a security breach.

There is a wide range of tools and practices used for cloud security. The most important function is to ensure that only authorized users access the data stored in the cloud.

Micro-segmentation divides the data center into different security sections, giving more focused control and lessening the damage that attackers can cause. Next-generation firewalls provide heightened protection against potential threats. Data encryption with an associated key offers another layer of protection. Threat intelligence is used to find and block malware and other disruptions. The expertise and resources of cloud providers give them a robust and advanced security approach.
