Cybersecurity is necessary for organizations wanting to guard against unauthorized access to their computer systems. There are increasing amounts of digital data, and cyber-attacks are becoming more commonplace. There are many cybersecurity methods, and one of them is two-factor authentication (2FA), which makes online accounts and computer systems more secure by asking for two separate pieces of information. Businesses are using 2FA to protect their company data. Cybersecurity specialists provide essential services to organizations that want to avoid the repercussions of cyber-attacks.

Where to Begin as a Cybersecurity Specialist
Cybersecurity specialists are in demand by organizations to keep information systems secure and guard against cyber-attacks. People who are interested in how to become a cyber security specialist could enroll in St. Bonaventure University’s Master of Science in Cybersecurity. Graduates of this course have a fundamental understanding of cybersecurity and cyber risk management. There are numerous fields within cybersecurity and an abundance of career opportunities. These graduates will have the knowledge to prepare businesses for maximum security, including the introduction of 2FA to their security infrastructure.
The increased frequency and sophistication of cyber-attacks means that cybersecurity professionals are in demand, and this is likely to grow in the coming years. Businesses and organizations need protection and keeping them safe has a positive impact on the economy and society as a whole. The Bureau of Labor Statistics predicts that cybersecurity specialist roles will grow 32% between 2022 and 2032, much faster than the average for most occupations. It is projected that there will be nearly 17,000 job openings over the decade.
Hackers exploit vulnerabilities like weak passwords, leading to numerous cybercrime incidents. Many users do not employ best practices when using passwords. If they have the same password across multiple accounts or a weak password, then there is an increased risk of security breaches. Strong passwords are long and random, with no obvious connection to the person. Password managers can store passwords securely, removing the need to remember every password. Users can utilize a generator or create complex passwords. Password managers use encryption to protect information. They synchronize passwords across different devices and perform other services, including notifications about fake websites and if passwords appear within a known data breach. Some password managers integrate 2FA on their platforms, increasing security and making data breaches less likely.
SFA and MFA
Single-factor authentication (SFA) requires only one type of evidence. The evidence can be biometric, such as a fingerprint, but it is usually a password. Although password use is not considered very secure, fingerprints are a secure method as they are difficult to fake. When the required information is provided, the online resource compares it with the information stored on the system. If there is a match, then the user will have access. If it does not match, then access will be denied.
Multi-factor authentication (MFA) is a procedure that requires users to provide two or more verification factors to access an online account, device or website. The factors would be a password, a one-time passcode, a facial scan, a fingerprint or all of these. 2FA is a subgroup of MFA and needs two factors to log in, whereas the MFA process requires a minimum of two. With machine learning and artificial intelligence, MFA can identify which staff need the most secure login processes and adapt the system accordingly.
2FA involves securely accessing online accounts or computer systems by requesting two separate pieces of information. The most commonly used security method is the username and password. However, using only SFA means that the username can be a recognizable name or an easily found email address. Most accounts rely solely on a password for protection.
To enable 2FA, the user needs to provide a username and password, and then prove their identity separately. Most 2FAs ask for something you know, such as a password or personal information, and another completely different factor. The factor could be a possession such as a smartphone or something inherent to the user, such as fingerprint biometrics. Both will be required to enter an account or computer system. With more data breaches and cyber hacks, passwords have become less secure. Businesses using 2FA have less chance of hackers accessing online accounts or corporate devices. There is more protection from cyber breaches and increased awareness of hacking attempts.
2FA involves a multistep process. Firstly, the user accesses the login page. They enter what they know, which is the username and password. The site’s server recognizes the user. If passwords are not being used, then the website produces a unique security key. The key is processed and validated. The second login step involves the user proving that they have something that no one else would have, such as an ID card. A one-time code is produced and entered by the user. Now, the user is authenticated and given access to the application or website.
Access control mechanisms are part of the core functionality of operating systems. Cybersecurity specialists must manage system, network, physical and application-level access using technical, physical and administrative security controls. Examples of technical access controls are software-based mechanisms for controlling access such as encryption, firewalls, passwords and intrusion prevention systems. Physical access controls include biometric readers, keypads, passwords, gates and locks. Administrative access controls can be an organization’s written access control policy, which outlines organizational processes for remote access, physical access, password requirements, logging and monitoring, auditing, adherence policies, and administrator and privileged accounts.
Identity and access management (IAM) is also a technical control. Some solutions help organizations manage and automate identity and access-related tasks, such as enrolling, managing passwords, modifying and disabling user accounts, authenticating users, authorizing users, and providing monitoring, logging, auditing and reporting capabilities. These solutions may also support single sign-in, so users can log in once and access multiple applications and systems.
The computing environment has changed, with many businesses using the cloud. IAM solutions are needed to restrict access to information stored on the cloud. Cloud-based access control is a physical security system that provides a better user experience. Using the cloud means that there is no need for computer resources or onsite servers. Cybersecurity specialists can use cloud-based security to create different access levels for users, give or deny access remotely, receive alerts when someone is trying to get unauthorized access, and set up time limits for certain entries. Authentication methods are used to verify the identity of users. Compared to traditional systems, cloud-based access control systems can be easier to use and monitor remotely, and have a lower cost.
2FA can work in two ways to control access for business organizations. It supports data access control and physical access control. Organizations limit who can physically access their offices through 2FA access control systems. Staff need an authentication factor such as tokens, biometrics or identity cards. Executives and management can decide who can have access to what information. Crucial data can be protected from general access within the same network or system. Only people with an authentication factor can access the information. Businesses that sell products online require customers to create a user profile, and 2FA can be used to ensure that only the customers access their accounts. 2FA helps businesses to build a strong adaptive security system.
Phishing attacks are becoming more common and can lead to significant financial losses. These attacks involve cybercriminals sending messages to users to gain sensitive information or introduce malware into the user’s system. Studies show that cybercriminals direct their attacks to mobile and personal communication channels.
A business email compromise is a phishing attack that emails business people about something that appears urgent. The message may ask for company information or bank account details. Company information could be used to open a fake bank account or kept for a data breach later. Whaling is another type of phishing that targets senior managers. Extremely sophisticated emails are sent and cannot be traced. Spear attacks sometimes target individuals, but the target is the organization. Emails are sent to employees using personal information or disguised as a reputable company. A link may connect with malware or to a website asking for more information. Alternatively, people may be asked to reply to the email with sensitive information.
2FA can help to protect against phishing attacks by making emails secure. Cybersecurity specialists can enable 2FA for all the emails of the business. If any credentials are at risk of attack, 2FA will not allow access. A code is sent to the registered phone number (usually the company’s), and without verification of this code, there is no email access.
Businesses are changing and becoming more technologically advanced and data-driven. Organizations must use technology to empower their workforce, use data analytics and operate efficiently. There are new industry regulations and standards relating to data and cybersecurity. Compliance is an official way to protect organizations from cybercrime. Organizations must be compliant by having risk controls that protect information. Complying with regulations and standards allows organizations to maintain security practices and operate efficiently.
Data breaches can damage an organization’s reputation and financial status. Legal proceedings resulting from a breach are happening more often across industries. Most data protection and cybersecurity laws relate to sensitive data, which includes financial information, protected health information and personally identifiable information. Examples are credit card numbers, medical history and date of birth. Other kinds of sensitive information, such as race, religion and marital status, may also fall under compliance laws. The benefits of complying with these laws are a good reputation, customer loyalty and improved security.
Currently, using 2FA to protect systems is not mandatory for all industries. However, 2FA is needed to comply with password restrictions in sectors such as healthcare, defense, finance, government and law enforcement. 2FA plays an essential role in compliance and best practices, and its use is likely to grow within industries and the overall environment.
Credentials refer to specific data or authentication tools used to verify a user’s identity so that they can get authorized and gain access to a network or system. Credentials are valuable when securing a company’s network infrastructure, protecting customers, employees and assets. Credential theft can cost companies millions and be very hard to detect. After a cyber-attack, businesses can assess their security systems and identify any weaknesses. Staff training can ensure that everyone in the company is able to recognize potential malicious activity. It is possible for users rather than technology to have contributed to the breach. Modules can fight against phishing attempts so that campaigns can be detected before causing any harm. Cybersecurity specialists can continually challenge security protocol and try attack techniques to monitor staff behavior. Introducing 2FA can improve security and thwart the collection of application or network credentials.
2FA can block an attacker from accessing a user’s account. If a cybercriminal steals a user’s password, they will not gain unauthorized access to the account because another verification method is required. Having two verification methods gives an added layer of security and considerably reduces the risk of access and data breaches. Financial institutions have acknowledged the value of 2FA in protecting their customers’ transactions and accounts. Their customers can feel that their financial information and identities are protected with a reduced risk of financial losses and breaches.
With companies allowing staff to use their own devices to access business data remotely, there are increased security risks. When there is just one password, it can be cracked or phished by cybercriminals. 2FA can prevent possible security breaches by adding an extra obstacle. By using 2FA, businesses can add additional security measures to remote access protocols so that only authorized users can access their computer systems. Sensitive data is protected, and it demonstrates to clients and stakeholders that the company is proactive regarding data security and takes action to protect shared information. Cyber threats are significantly higher when 2FA is not in place. Breaches can be damaging, resulting in reputational harm, productivity slowdowns and financial loss. It can be time-consuming and costly to recover from a data breach.
When remote access protocols have 2FA, security is enhanced by the added layer of protection. Cybercriminals are deterred when unauthorized access is more difficult to achieve. 2FA protects against cyber threats such as phishing and brute force attacks. Phishing is when cybercriminals deceive people into revealing sensitive information such as passwords. However, if they obtain passwords, they still cannot gain access without having the second verification step. With brute force attacks, hackers use software to try different password combinations, but this will not work with 2FA. More people work from home and use their devices to access business accounts. Using 2FA gives increased security and mobility. Employees can securely access their business accounts from any location, and sensitive data is protected.
As the field of cyber security continues to evolve, the future of 2FA shows potential. As cyber threats become more sophisticated, it is essential to have measures for identity verification. One growing trend has been the use of biometric methods. Technology advancements such as finger or face recognition, voice authentication and iris scanning will provide convenient and secure means of identification. There is interest in passwordless authentication, where other options such as biometrics or keys replace traditional passwords. There will still be password-related attacks. It is expected that fitness trackers and smartwatches will be used by 2FA by giving authentication through biometric sensors. The arrival of Internet of Things (IoT) devices also has possibilities for using 2FA, with connected devices being able to interact safely.
Intelligence and machine learning advancements will allow highly developed behavioral analysis techniques that bring adaptive and dynamic authentication processes. As technology usage increases, the defense against attacks and decentralized nature of 2FA solutions are likely to lead to their wider adoption. Advancements in wearable devices, blockchain-based solutions and passwordless authentication methods have expanded the scope of 2FA and ensured that there are security measures to guard against evolving cyber threats. Technology continues progressing, and innovative authentication techniques emerge, with 2FA becoming an essential part of data security.
Cybersecurity is essential in helping organizations keep their computer systems safe. Cyber-attacks are increasingly common, and cybersecurity specialists use different methods and techniques to protect data. 2FA is a method that ensures the secure access of online accounts or computer systems by requiring two separate pieces of information. 2FA brings many benefits to businesses, such as enhanced access control, safer remote working, and protection against phishing and credentials being stolen. 2FA plays a part in compliance and best practices and will likely be used increasingly across industries. 2FA is an innovative authentication technique that has become essential to data security.
