We live in a technologically saturated world. Everyone is connected to one network or another by any number of devices, so that begs the question: “Just how secure are those connections?” Earlier this year, headlines were made when a hospital in California (and several others in other states shortly thereafter) had its network system hacked; its files and patient information encrypted and held ransom. To gain access to their own files, the hospital paid the hackers for the encryption key so that they could continue providing their patients with the much needed medical care they were seeking [1]. More recently, it was reported that over 6,000 online stores had malicious code, designed to steal and store credit card information, hidden within
It can be very expensive; costing hundreds of dollars for each stolen record. It’s challenging to prevent when hackers constantly update and change their patterns faster than the software designed to stop them is updated. Adding to that, users who try to circumvent security policies they find annoying or restrictive [3]. Another point of possible breach is employees accessing the network via personal devices (tablet, phone, usb) [4], poor network access passwords, and outdated server software. Even web cookies have the potential to provide access to private information [5]. There is no shortage of vulnerabilities that exist within any network and now some of the securities that are in place have been under discussion on just how “secure” they should be. Last year the terrorist attack in San Bernardino not only caught headlines because of the attack, but also because shortly thereafter there was a standoff between the FBI and Apple due to Apple’s refusal to crack the terrorists phone for the FBI. Apple stated that, “Up to this point, we have done everything that is both within our power and within the law to help them.” It continued, “But now the U.S. government has asked us for something we simply do not have, and something we consider too dangerous to create. They have asked us to build a backdoor to the iPhone.” [6]. Since the FBI vs Apple case, regarding the complexity of the encryption Apples uses for its devices, encryption backdoors have been a hot topic. Apple argues that having one defeats the purpose of the encryption, making it easier to access and exploit data [7(a)]. Having encryption and Firewalls bring a peace of mind but vigilance, constant upkeep, and caution on the users end are also required for network security. Backing up data, avoiding a single point of failure, and making sure data is only put where it needs to be are a few extra precautions to keeping your network secure

    Should Apple be forced to unlock an iPhone or not? It becomes a controversial topic during these years. Most people are concerned with their privacy and security. Darrell Issa is a congressman and has served the government since 2001. Recently, he published “Forcing Apple to Hack That iPhone Sets a Dangerous Precedent” in Wired Magazine, to persuade those governors worked in the Congress. It is easier to catch administrators’ attention because some of them want to force Apple to unlock the iPhone. Darrel Issa focuses on governors because he thinks they can support the law to make sure that everyone has privacy. He addresses the truth that even some of the governors force Apple to hack iPhones when they need people’s information. He considers maintaining people’s privacy as the primary purpose. He also insists that Apple should not be forced to use their information which could lead people’s safety. In “Forcing Apple to Hack That iPhone Sets a Dangerous Precedent,” Darrell Issa uses statistics and historical evidence to effectively persuade his audience of governors that they need to consider whether or not Apple should be forced to hack or not because it could bring people to a dangerous situation and forget the purpose of keeping people’s privacy.

    The San Bernardino vs Government case has been in the news for the last months since the terrorist attack last December. It has reminded the world the importance of encryption which is essential for our lives and privacy in this new era of technology. After the attack, the FBI asked Apple for help to access an iphone that belonged to Syed Rizwan Farook one of the perpetrators of the attack, Because the FBI could not access it due to the modern encryption and security features new iphones have. Apple was not completely oppose to help the FBI. The company helped with everything could without violating the privacy of its customers. Apple gave access to the backup data stored in iCloud from Farook’s iphone, but the data obtained was six weeks prior to attack. The FBI still needed more private information from the iphone such as, texts, phone calls and GPS locations after the attack. Apple is now being forced by the federal court to create a software to bypass the security features of the iphone to completely access its data. Apple is refusing to create this software because the company says this would put in danger the privacy of every Apple customer. The company says that once they create this backdoor to the iphone, they cannot guarantee to keep it safe. Because once created it can be modified to open infinite amount of iphones and access their data. Many people are concern about this issue and most experts agree that if the program is created more security issues will arise, not only within individuals, but national and possibly international security issues since technology is now all over the word.

  • Privacy vs. Security

    1260 Words  | 3 Pages

    Ever since day one, people have been developing and creating all sorts of new methods and machines to help better everyday life in one way or another. Who can forget the invention of the ever-wondrous telephone? And we can’t forget how innovative and life-changing computers have been. However, while all machines have their positive uses, there can also be many negatives depending on how one uses said machines, wiretapping in on phone conversations, using spyware to quietly survey every keystroke and click one makes, and many other methods of unwanted snooping have arisen. As a result, laws have been made to make sure these negative uses are not taken advantage of by anyone. But because of how often technology changes, how can it be known that the laws made so long ago can still uphold proper justice? With the laws that are in place now, it’s a constant struggle to balance security with privacy. Privacy laws should be revised completely in order to create a better happy medium between security and privacy. A common misconception of most is that a happy medium of privacy and security is impossible to achieve. However, as well-said by Daniel Solove, “Protecting privacy doesn’t need to mean scuttling a security measure. Most people concerned about the privacy implications of government surveillance aren’t arguing for no[sic] surveillance and absolute privacy. They’d be fine giving up some privacy as long as appropriate controls, limitations, oversight and accountability mechanisms were in place.”(“5 Myths about Privacy”)

The growth of mobile computing in both the workforce and for personal use has also caused a growth in the malware and mobile botnets available to mobile devices (Symantec). To be able to properly protect the mobile device and environment, security teams should be looking at building in and not just bolting on security mechanisms. It is a fairly common saying now among security professionals that it is not if you are hacked or breached it is a matter of when. However, by using common sense and choosing methods that offer a better defense strategy, users and security organizations can minimize or greatly reduce the likelihood of sensitive data loss.

    Apple argues that, “Compromising the security of our personal information can ultimately put our personal safety at risk. That is why encryption has become so important to all of us” (Cook). Many others argue with Apple that loss of privacy leads to loss of security. Although that may be true if the information is ending up in the wrong hands, the FBI is using this information to protect the well-being of American citizens. According to USA today the fear for lack of privacy, “is counterbalanced by the need for public security in an age when terrorists use encrypted smartphone communication to secretly plot devastating attacks such as the recent suicide missions in Brussels and Paris” (Johnson, Swartz, and Cava) . Encryption is a useful tool for those who know how to use it responsibly. On the contrary, necessary action is taken against those who misuse it. When encryption falls into the hands of terrorists, it is more important to retrieve the deadly information than to risk less dangerous data being deciphered as

Despite the massive threat the problem poses, no one has yet to institute an effective solution. Although government regulation and website blocking attempt to eliminate cybercrime and cyberwarfare, an ideal solution exists in government guidance and collaboration with the private sector.

Many hackers attempt to gain access to people's personal medical files in order to blackmail them, or to avenge some injustice by spreading the person's health problems around. Other possibilities might go as far as to include looking up a patient's current location, in order for gang members to finish off the survivor of a drive-by shooting or other attempted murder. It is for these reasons that medical facilities computer security procedures are second only to the government's (Shoben).
