Public Key Infrastructure : Digital Communications And Information Security

6) PKI-Enabled Applications: For any product applications to be taken inside the Public Major Infrastructure (PKI), they ought to be PKI-empowered. {In other Quite essentially, it basically implies that the applications or programming ought to be equipped for comprehension and making utilization of computerized records. Such PKI-empowered application programming ought to have the capacity to verify remote clients and furthermore validate the product itself for remote clients while in a PKI.

In today’s world of instant connectivity and information at users’ fingertips, it’s vital that sensitive information is safeguarded against those who seek to do personal harm and profit from gaining access to the data. The key behind keeping information safe is the method in which it’s protected and encrypted. In order to appreciate how information is secured, users must understand the encryption concepts behind it. To do this, one must comprehend the current encryption standards, the trends and developments in encryption technology, the importance of securing data, the government’s regulations pertaining to encryption, the companies involved in research and implementation, the implications of leaked or stolen data, and a brief look into

Richman Investments needs a new enterprise encryption strategy. Richman Investment plans on expanding to 10,000 employees in 20 countries; there is a need for a more secure network. There are many difficult tasks that need to happen to make this a reality. It takes a lot of work to have a secure network and it needs to be monitored 24 hours a day 7 days a week. The best route to accomplish the company’s goal is a public key infrastructure (PKI). One security option that should be used is the Privacy option for confidentiality. This will help keep confidential information from prying eyes unless the user is authorized. Sensitive information such as SSN, personal home addresses and phone numbers, or other personal information will be kept

Security is the heart of internetworking. The world has moved from an Internet of implicit trust to an Internet of pervasive distrust. In network security, no packet can be trusted; all packets must earn that trust through a network device’s ability to inspect and enforce policy. Clear text (unencrypted data) services represent a great weakness in networks. Clear text services transmit all information or packets, including user names and passwords, in unencrypted format. Services such as file transfer protocol (FTP), email, telnet and basic HTTP authentication all transmit communications in clear text. A hacker with a sniffer could easily capture user names and passwords from the network without anyone’s knowledge and gain administrator access to the system. Clear text services should be avoided; instead secure services that encrypt communications, such as Secure Shell (SSH) and Secure Socket Layer (SSL), should be used. The use of routers and switches will allow for network segmentation and help defend against sniffing

Since the onset of the first packet switching event that many believe to be beginning of the internet, no other technology besides the printing press has ever transformed the ability to deliver information. Although the internet is used by a large percentage of the civilized world, few Americans realize how vital cyberspace is to our national infrastructure. Today, we are faced with even more threats although it has been a recognized problem since 2009, when President Barrack Obama said “The cyber threat is one of the most serious economic and national security challenges we face as a nation. It’s also clear that we’re not as prepared as we should be, as a government or as a country (Obama, 2009).” Every industry that operates in the United States is dependent on the internet for some aspect of their business. Commerce, transportation, financial institutions, military, as well as industrial control systems are all interconnected. This interconnectedness has created vulnerabilities within their infrastructure that have increasingly become targets of terrorists, script kiddies, foreign governments and hackers of all types.

a) A PKI (public key infrastructure) enables users of a basically unsecure public network such as the Internet to securely and privately exchange data and money through the use of a public and a private cryptographic key pair that is obtained and shared through a trusted authority.

With the world becoming more advanced and more and more devices being conceived, ie. Smartphones, Smart car, and Smart house, along with a growing dependence on, them even on the level of the government, we need to protect our privacy and safety. It has been statistically shown that our safeguards against hackers and foreign threats is severely lacking. Still, this a worldwide problem, and with the technological revolution, people don’t know how to keep their information safe, so it is our job as part of the government to protect our citizens even from digital

The Public Key Infrastructure (PKI) can be as strong as we want to design the system. Public Key Infrastructure (PKI) adoption is necessary in order to stay competitive and secure in today’s world. After implementation, data will more secure, customer will have more trust in operations, and this company will be compliant for years to

The in-house approach provides the maximum level of control. Certificates and keys can be made any time with little wait time. However, the cost of software licenses, maintenance fees, and the expense to purchase and deploy the entire supporting infrastructure can be big. Also add in training of a few employees or hiring new ones with the needed skills. The cost will pay for its self eventually. (Walder, Bob. July 2003)

(Public Key Infrastructure Roadmap for the Department of Defense, Version 5.0, 18 Dec 2000, p.6) The overall IA posture was balanced on the DoD’s Defense in layering strategy allowing the use of multiple solutions of varying assurance levels in which to prevent or contain the consequence of a breach of security. The Defense in layering strategy coined Defense in Depth, consists of five layers: Defense of Computing Environments including the hosts, servers, applications, and operating systems used within DoD local area networks (LANs), Defense of Enclave Boundaries/External Connections at which DoD LANs connect to the wide area networks (WANs) by deploying boundary protection measures to control and monitor access to the internal LANs, Defense of Networks and Infrastructure, including the WANs that are used to interconnect DoD systems and those of its allies and business partners, to ensure the confidentiality of DoD communications and protection against Denial of Service attacks that could disrupt DoD’s ability to communicate prior to or during operational deployments, Attack Sensing, Warning, and Response to protect, analyze, and respond to unauthorized access, intrusions, and cyber attacks at local, regional, and national levels, and Key Management Infrastructure (KMI) services including key management for DoD traditional and more recently public key systems, as well as physical products such as codebooks and authenticators. A component of the KMI is Public Key Infrastructure (PKI), which consists of products and services, which provide and manage X. 509 certificates for public key cryptography. This paper

Throughout time, privacy and security have been two heavily debated topics. There has always been a struggle to find middle ground between a private environment and a secure environment, but the dawn of technology and the Internet has made this struggle even more difficult. The Internet has drastically decreased the expectation of privacy of any and all individuals that have ever used it. Technology in general can pose a threat to an individual’s physical and virtual security. The Internet has also brought forth a sense of anonymity to those looking to conceal their true identities, some of which plan to commit horrific crimes. Privacy and security go hand in hand, however security is by far the most important.

The digital age provides individuals with numerous ways of innovative opportunities like recording data in an effective manner, electronic banking, online shopping, by violating privacy. Despite what might be expected, the national and global security framework needs components to check programmers and outsider interceptors, who can access delicate data and information, placed in various divisions of the financial framework. These outsider interceptors can then break-in remotely to harm or get access to passwords and usernames.

The internet is a medium that is becoming progressively important as it makes information available in a quick and easy manner. It has transformed communications and acts as a global network that allows people to communicate and interact without being limited by time, boarders and distance. However, the infrastructure is vulnerable to hackers who use the system to commit cyber crime. To accomplish this, they make use of innovative stealth techniques for their malicious purposes in the internet.

We are living in an information-driven world today that requires us to protect what and how we share this information. To access the guarded data or information we want to protect requires either a password or a pin. A password is a string or group of combined characters precise in length. Passwords and pins are suppositional, and more consideration is seriously required. They are the primary defense against intrusion. However, they can be easily captured and deciphered by cyber criminals. The security in this area is challenging due to the ineffectiveness of the creation of passwords and pins. Kirushnaamoni (2013) elicits that making logging in straightforward and convenient for users and trying to prevent password cracking is problematic. Cyber criminals will continue to persist and target the vulnerabilities in this area. Therefore, personally, financial, health and

As global security continues to grow exponentially in response to threats of cyber terrorism, the field of computer security continues to proliferate into many adjacent socioeconomic and technologically-based areas of society. Gartner Group, a leading market research in the enterprise IT industry, has stated that the worldwide market for security software will reach $21B in 2011, rising to $15.8B in 2015 (Karjalainen, Siponen, 2011). This rapid growth of computer security is also driving the development of entirely new patents in the areas of cryptography, enterprise security management strategies, and extensive support for more advanced programming features for securing enterprise networks (Albrechtsen, 2007). The pace of development in this market is accelerating as the sophistication and variety of threats continues to also exponentially escalate (Liang, Xue, 2010).
