  • Challenges of Internet Security

    The primary challenges of Internet security have everything to do with balancing accessibility and functionality with the three pillars of information security: confidentiality, integrity and availability.

    The Internet has become an in disposable tool for research, commerce, art, education and virtually every part of modern life. It was the inquisitive, intelligent, intuitive and creative nature of humanity that created the Internet and its those same qualities that put individual systems linked directly to the Internet in peril. The three pillars of information security are at stake for all systems with connectivity to the Internet. The challenge is in the implementation of the necessary security controls to achieve those three pillars.

    Confidentiality:

    Confidentiality pertains to protecting sensitive information. Sensitive information can be anything from private user information to classified defense data. Many organization live and die by the protection of proprietary information from competitors. During wartime, the armed services literally LIVE or DIE based on how well certain sensitive information is guarded. In the US Department of Defense is called Operational Security. Since the Internet is a critical part of the DoD (and defense organizations around the world) the confidentiality is a HUGE challenge for their Information systems exposed to the Internet. Some of the threats to there systems include: social engineering, leaks of information and accidental release of sensitive data. All of these threats can be enabled via the Internet.

    Organizations must educate their user who have access to sensitive information. I’ve heard some security professionals say that educating users is bad.

    But if your users have access to sensitive information (and need to have that access to do their jobs) it is imperative that they not only know WHAT is sensitive, but WHO it can be give to, WHEN it can be shared, HOW it can be share and WHY it can be shared.


    Integrity:

    Data integrity is very important to all systems passing data on the Internet. Integrity has to do with whether or not the message on the other end of your connection is the same one you actually sent. Whether its your passwords being passed to your bank or the DoD passing data over the Internet, the integrity of the data is imperative. Its often taken for granted until, we are sending an email and the receiver says they got the email but the message can’t be read. Sometimes if the messages integrity is garbled or malformed it simply won’t reach its destination. If the integrity of a message can not be protected in some way or verified and checked, it is possible for someone to intercept your message, alter it, and send it on its way. Integrity is especially critical in banking and financial transactions which is why encryption and authentication take on such an important role for sensitive transactions such as ATM withdrawals, and online banking.

    The challenge to maintaining Internet integrity is to ensure that link is encrypted when necessary.


    Availability:

    If there is no availability there is no mission, no business, no functionality. One of the major challenges of Internet security has been Denial of Services attacks. A Denial of Service attack is when your system on the Internet (or within a network) is flooded with useless traffic such that no one else (not even you) can use it. With a misconfiguration, a denial of service can happen by accident. Its important to test the availability of an online system. Its also a good practice to see what kind of availability and access you are giving. After all, too much availability can compromise the security of your system.

    Most challenges of Internet security can tie into one or more of the big three: confidentiality, confidentiality or availability. With those in mind most challenges can be overcome. But the double edged sword of security.. the very nature of it on the Internet is to constantly change and evolve with the Internet. The constant change of threats to those three aspects of security is perhaps the biggest over arching challenge.

  • Dangers on the Internet

    Dangers on the Internet
    This is a follow up to my post Why is Internet Safety Important

    Dangers of the Internet are relative to the perspective of those accessing it. That is to say, on the Internet “dangers” are completely dependent on who is accessing what data from where and what their intentions are for accessing it. For example, researching a list of poisons could be a considered “dangers to the Internet” if a seriously disturbed person intends to kill his or her spouse. On the other hand, if a parent is just wondering what house hold products are poisonous with the intention of protecting her children, can that be considered a danger?

    So protection from dangers on the Internet should be proactive and involve human judgment at some level. Policies must be written, planned and implemented in advanced or ad hoc to suit the environment and the users accessing the Internet. Children at a school with access from the classroom will more than likely be different from employees at a skating rink.

    Even the items commonly considered dangers on the Internet relate directly to how much access individuals and organizations allow to and from the web. Common “dangers” may include (but should not be limited to) the following:

    Accessibility to personal – applies to educating users on the dangers of putting personal information on the Internet and protecting organizational data bases

    Sensitive data – For a school sensitive data is likely linked to the grades and personal information of staff and student, but for a business sensitive information could include proprietary information that would hurt the bottom line if it were leaked to competition.

    Financial fraud & criminal hackers/scammers- This applies to educating users about criminal hacker techniques such as malware, social engineering, email and website phishing

    The access of impressionable and/or psychologically disturbed individuals to potentially harmful and destructive information – This is rather subjective however it should be a concern to schools from elementary – colleges, rehabilitation facilities and mental institutions. There are ways to block certain obvious material with web-blocker type applications, but no one can stop them all. Monitoring is a must if this danger is to be handled seriously.

    The risks and damage of these dangers are dependent on the environment & the users involved. It is up to the system owners to ensure that the policies are properly planned, implemented and maintained as exposure to any Internet danger can disrupt the safety, mission and/or values of an organization or individual.

  • Why is Internet Safety Important

    Dangers on the Internet
    The amazing freedom and availability of the Internet lends itself to a few major dangers: Pr0n, malware and how to perform illegal and/or dangerous activities.

    Whether it is a curious person seeking these things out or the child accidentally clinking the wrong link and getting bombard with explicit pop-ups, the items lists can be harmful to an impressionable mind. Policies must be enforced.

    There are a few groups that should have limited exposure to certain types of information on the Internet. Children, mentally handicapped or psychologically damaged people in settings such as schools, homes, rehabilitation or correctional facilities and group homes should be blocked, tracked and monitored while accessing the Internet. Certain information could destroy them if they don’t yet have the capacity to understand or put certain information in the proper context.


    Protection from Pornography & Malware

    In a professional setting there should be a written policy against accessing and/or downloading unacceptable material such as pornography. These items should be actively blocked whether in a working environment or at home among minors accessing the same system. Allowing impressionable or fragile minds unlimited access to certain graphic material is irresponsible. The law is also a good reason why Internet safety is important. If you are the owner or charged with immediate control of the system being used for illegal activity, you could be partially or wholly liable for the activity. An example is substitute teacher Julie Amero

    On October 19, 2004, Julie Amero was substituting for a seventh-grade language class at Kelly Middle School in Norwich, Connecticut. The teacher’s computer was accessed by pupils while the regular teacher, Matthew Napp, was out of the room. When Julie took charge, the computer started showing pornographic images.

    On January 5, 2007, Amero was convicted in Norwich Superior Court on four counts of risk of injury to a minor, or impairing the morals of a child. Her sentencing was delayed four times after her conviction, with both the prosecution and judge not satisfied that all aspects of the case had been assessed.[1] The felony charges for which she was originally convicted carry a maximum prison sentence of 40 years

    – wikipedia

    The Kelly Middle School systems were actually infected with malware that allowed the explicit pictures to pop up.

    Access to Dangerous information

    From the Columbine shooters to the Virginia Tech massacre, most of the killers had a recorded history of mental illness and/or psychologically instability. In many cases, they used public and/or home computers belonging to their parents to research bomb making or even purchase guns.

    Controlling access is the best way to get on the Internet safely. Maintaining privacy of users is another important step in Internet safety, however that is a matter of educating users particularly if the frequent Social networks such as facebook or myspace. They need to be instructed about the dangers of stalkers, perverts and predators looking specifically for impressionable minds.

    We are the keepers of these impressionable and fragile minds. That is the reason Internet safety is important and why we must be mindful of these subjects.
