Comparison of VoIP and TETRA Regarding Security in a Safety Critical Environment

In this document, University of Applied Sciences FH Technikum Wien (Vienna, Austria) analyze security threats on VoIP (Voice over IP) and TETRA (Terrestrial Trunked Radio) solutions and mitigation techniques.

 

Conclusion

“We recommend Tetra for safety critical environments like vessel and port terminal operations, Airports and government emergency authorities. Any place using Tetra should have a backup plan or plan B in case of unsolved attack or disaster. Backup could be using VOIP app, GSM (Global System for Mobile communications) with push to talk feature and many other applications can be used. VoIP can be used mainly in private communication with taking all security countermeasures into action to mitigate risks on Confidentiality, Integrity and Availability.”

Georgia staffer fired after arrest for eavesdropping and drug charges

ATHENS, Georgia — Georgia has fired an assistant equipment manager who was arrested Friday night on felony eavesdropping and drug charges.

James Kevin Purvis, 37, was being held Saturday morning in the Athens-Clarke County Jail on $16,000 bond. He faces three felony counts of eavesdropping or surveillance, felony possession of schedule II controlled substance and misdemeanor possession of marijuana.

Georgia spokesman Claude Felton said the athletics department notified UGA police of the incident, and Purvis was fired early in the investigation.

“As soon as it learned of the incident, the Athletic Association notified the University of Georgia Police Department, who began their investigation,” the statement read. “The University took immediate action, and the employee was terminated early in the investigation. Based on the findings of the police investigation, no student-athletes were victims in this incident.”

The Atlanta Journal-Constitution reported Saturday morning that an unidentified person discovered a camera hidden in the shower area of Butts-Mehre Heritage Hall. UGA officials notified police on Feb. 27 and officers searched the football team’s locker room, training facility and weight room, as well as Purvis’ car and home.

Purvis is a native of Ocilla, Georgia, and has worked as an assistant equipment manager with the Bulldogs since 2006, according to the athletic department’s website. He held a similar position at Valdosta State University.

Reasons Why You Should Start Using VPN

You may already know what a VPN (virtual private network) is but there is also a very good chance that you never use one. With the continued increase in the number of online threats, it makes more sense to protect yourself in all your online activities. Having the right antivirus software installed is not enough. For an added layer of protection, you should consider using a VPN.

A VPN is basically a group of computers that have been networked together over a public network (Internet). To use a VPN, you launch the VPN client on your computer then log in. Thereafter, your computer will start exchanging trusted keys with distant servers. Once the two computers verify your authenticity, all your communication will be secured from any form of eavesdropping. This is done by encrypting communications. The important point to understand about VPNs is that they will secure your internet connection by guaranteeing all the data you send or receive is encrypted and safe from eavesdropping.

Why use VPN?

There are many reasons why you should consider using VPN, whether you are a student, an IT expert or anybody looking for more security when using the Internet. Here are the top benefits you stand to gain.

Enhanced security

The main reason why most people go for the VPN is to enjoy enhanced security. Once you connect to a VPN, all your only activities will be encrypted. Your information will therefore be safe from hackers.

Remote control

VPN has been found to increase productivity in a company. This is because once a VPN has been set up, information can be accessed remotely and securely. This means employees can work from home or anywhere without compromising the security of company information. All that is needed is for an employee to have the right login credentials. The VPN can further be used to share files for an extended period of time with a group.

Online anonymity

Most people go for the VPN because of the benefit of online anonymity. A VPN allows you to browse the internet anonymously. Not even your ISP will be able to keep tabs on your online activities. The VPN will also hide your real IP address and allow you to access websites and web applications anonymously. To learn more about this, please visit fastestVPNguide.com.

Bypass filters and unblock websites

When travelling, you will not be able to access certain websites that are restricted to certain regions. A VPN can help you unblock such websites. It helps bypass Internet filters so that you can access just any website that you want. You can also change the location of your IP address so that if you want to access content restricted to the US and you are in Australia, you can just select an IP location in the US.

There are so many benefits that come with the use of a VPN. At the end of the day, you will notice better performance thanks to improved bandwidth and efficiency of the network and reduced overhead costs. The most important thing you need to do is to pick a VPN provider that will not limit you.

Swiss prosecutors charge Germans with industrial espionage – report

BERLIN/ZURICH (Reuters) – Swiss prosecutors are charging three Germans with industrial espionage and violating bank secrecy, a media report said on Tuesday, potentially stoking a simmering dispute between Germany and Switzerland.

Zurich prosecutors allege the individuals passed documents to German courts and authorities, several Swiss and German media reported, in the latest twist to a row pitting Switzerland’s long-defended bank secrecy laws against a German tax clampdown.

The issue should be examined by the German government, said Lothar Binder, the financial policy spokesman for the Social Democrats in the German parliament.

“We need to ask what the legal basis the Swiss government is following here,” he told the media groups behind the report. “Perhaps they are trying to set an example to deter others.”

The Zurich prosecutor’s office was not immediately available for comment, while a German foreign ministry official said it was familiar with the case but that it does not comment on ongoing judicial processes.

The Swiss justice ministry had empowered the Zurich state prosecutor to investigate the three people on possible charges of industrial espionage in 2015, the media report by German weekly newspaper Die Zeit, the Correctiv research group, German broadcaster ZDF and Swiss digital magazine Republik, said.

The report, a summary of which was released to German media, said the three individuals – a Stuttgart-based attorney for Mueller and two bank employees – have denied the charges.

German states have for years obtained details of bank accounts held secretly in Switzerland by Germans they say are trying to evade tax. Swiss authorities say this amounts to the theft of business secrets.

The Swiss Banking Act requires employees of Swiss-regulated banks to keep client information confidential, but a number of staff have leaked account details to foreign authorities in the past decade as Western governments crack down on tax evasion.

Such whistleblowers and new disclosure standards have proven costly for Swiss banks, which have suffered hundreds of billions of dollars in outflows as a result and more than a third of Swiss private banks have closed.

The latest case stemmed from a legal dispute between private Swiss bank J. Safra Sarasin and German investor Erwin Mueller concerning “Cum Ex” trades which made use of a capital gains tax loophole that has since been outlawed, according to the report.

AG’s office accused of eavesdropping in suspected cop killer’s case

ALBUQUERQUE, N.M. — The Bernalillo County Law Office of the Public Defender is accusing prosecutors of the New Mexico Office of the Attorney General of eavesdropping on protected jail conversations between accused cop killer Davon Lymon and his public defender.
Lymon is charged with the shooting and killing of Albuquerque Police Department officer Daniel Webster during a motorcycle traffic stop in 2015.

Attorney-client privilege is intended to keep communications between a client and an attorney secret. However, since Lymon is in jail many of his phone conversations and visitors can be surveilled. Of course, one of Lymon’s visitors is his public defender. Of course, Lymon’s public defender contacts him.

In a March 15 filing, The LOPD accused the AGO of listening to Lymon’s conversations with his public defender. The filing comes days after District Judge Briana Zamora kicked the LOPD off Lymon’s state case ruling representing him was a conflict of interest.

 
The woman reported to be on the back of Lymon’s motorcycle the night of the deadly shooting was 19-year-old Savanna Garcia. The LOPD also represented Garcia when she was a witness in Lymon’s federal trial. Since the two are connected to the same incident, LOPD can’t represent both Lymon and Garcia.

The AGO responded to LOPD’s filing alleging that public defender calls made to the jail are not recorded.

Spokesperson James Hallinan sent KOB the following statement:

“The Office of the Attorney General is committed to seeking justice for Officer Webster and his family. The Court previously ruled that the Law Office of the Public Defender could not represent the Defendant due to a conflict of interest and denied the public defender’s motion to reconsider this afternoon. The Office of the Attorney General disproved these baseless assertions in a March 16 pleading.”

The LOPD contracts with private attorneys when a conflict of interests arises. At this time, it is not clear who will represent Lymon in his state trial.

Eavesdropping over Visible Light, research confirms that is possible and the attack is less limited

Visible light communication (VLC) is one of the newest technologies that has been developed for short and middle range data communication, as a commercial solution is predicted to have a considerable market penetration in the near future due to the advantages the technology brings. VLC provides a flexible communication channel that, according to the standard [2], allows data transfer rates ranging from 11.67 kb/s to 96 Mb/s.

Among the multiple benefits that VLC is supposed to bring into the market is the inherited security of the technology. This assumed security is based on the premise that (indoor) light data streams cannot be captured from outside users.

The work, “Study and Validation of Eavesdropping Scenarios over a Visible Light Communication Channel”, conducted by Ignacio Marin-Garcia, Victor Guerra and Rafael Perez-Jimenez proposed the study of eavesdropping on a VLC link. To accurately assess the possibilities of such an attack, simulations and practical experiments were performed.

The results seem to validate that it is possible to eavesdrop on a VLC-based channel from outside the premises and proved the validity of using geometrical considerations to define potential attacks zones.

Racine County Sheriff’s expects hundreds of victims from gymnastics coach with hidden cameras

RACINE COUNTY, Wis. (CBS 58) — The Racine County Sheriff’s Office has released new information about the gymnastics coach accused of setting up a hidden camera to watch people undress and go to the bathroom. 

According to the Sheriff, James Kivisto had 803 registered children at his gymnastics facility, Wind Lake Gymnastics Center, since it opened in 2007. Kivisto has been around Milwaukee and Racine Counties since 1987. 

49-year-old Kivisto is facing ten felony counts of child porn.

The Sheriff’s Office has already received 150 phone calls of parents and children worried they might be victims. The Sheriff expects hundreds of victims. They discovered over 100 inappropriate images on Kivisto’s devices which he admitted to viewing.

In an interrogation, Kivisto said he did not distribute the images but the Sheriff’s Office has not been able to confirm that information. 

Over the coming weeks and months the Sheriff’s Office expects it will conduct hundreds of interviews with possible victims and their families. Anyone who thinks they may have been impacted or anyone who ever went to Wind Lake Gymnastics Center is asked to call a hotline at 262-636-3990.

Kivisto told officials that he was arrested by Glendale Police in 1999 for child porn. The FBI was brought in and charges were referred to the Milwaukee County DA. What happened after that referral is unknown, but Kivisto was not registered as a sex offender.

The Milwaukee County DA’s Office sent CBS 58 this statement:

“This office routinely charges cases like the matter involving Mr. Kivisto in 1999. I have no further information about that charging decision from 19 years ago.This office routinely charges cases like the matterinvolving Mr. Kivisto in 1999.  I have no further information about thatcharging decision from 19 years ago.”

The hidden cameras were found by a family cleaning up after a party that was held at the Gymnastics Center.

No assaults were ever reported regarding Kivisto and officials never received a complaint. 

Kivisto was the owner/operator of the Gymnastics Center where he also lived. He was never married and had no children. He is being held on $150,000 cash bond. He is due in court next on March 21.

GBI investigates recording device found inside Worth Co. Jail

SYLVESTER, Ga. (WALB) — The Georgia Bureau of Investigation is looking into the discovery of a possibly illegal recording device inside the Worth County Jail.

The Tifton Judicial Circuit District Attorney’s Office was notified late last month of a device in the privileged attorney-client interview room at the jail.

Prosecutors say it was installed at the direction of now suspended Sheriff Jeff Hobby.

Attorney Mark Brimberry says Georgia Law explicitly prohibits a person recording a conversation in which he or she is not a party to.

But it’s obviously illegal to record a privileged conversation between an attorney and a client.

“That’s wrong, it should not have happened,” said Brimberry. “We’re talking about a recording device which they know when they put it in there and they certainly turned it on they knew they were violating the law.”

No interviews have been done in the room since the device was found.

It is now being looked at by the GBI Child Exploitation and Computer Crimes Unit.

Man arrested for hidden cameras in woman’s home

  • A man in his 20s was booked without detention for installing cameras in and outside a woman’s home, Busan local police said Tuesday.

  • The man is charged with entering the victim’s residence 12 times while it was empty and installing the hidden cameras inside the home.

According to the police, the man spotted the victim in January around the Haeundae neighborhood in Busan and tracked her to home. The man installed a camera in the form of a black box outside the woman’s door to discern the code to the door lock.

The 27-year-old is also being charged with hanging pornographic pictures on her door twice.

The man, masked and gloved, was caught by a neighbor who saw him inside the woman’s house on Feb. 16. The man reportedly admitted to his actions during interrogation when presented with CCTV footage.

Police said “the hidden cameras were so small that it was not easy to discover them unless you looked very closely.”
