Whatsapp security
It is important to be safe when using WhatsApp. Do not leave your phone unattended when you are not close by.

There are 2 billion WhatsApp users in the world, and 1,6 billion WhatsApp users access their accounts on a daily basis.

However, it is important to also be safe when using this popular communication tool.

According to Cobus van Jaarsveld, Assistant Director: Threat Detection, Investigations and Liaison in Protection Services, it does happen that people’s WhatsApp accounts get hacked; this is a serious violation of privacy.

“It means a third party now has unlimited access to your personal chats, information, media – and in some instances, they can also masquerade as you by deleting your chats, replying to your chats, and committing crimes. That’s just the tip of the iceberg of how harmful it can be to get hacked,” says Van Jaarsveld.

He adds: “Hackers can access your WhatsApp data by various means, e.g. via WhatsApp web or registering your number on another device.

The South African Police Service (SAPS) provided the following tips to prevent one’s WhatsApp from getting hacked:

• Log out from all computers that you see in the list under WhatsApp Web. This will stop hackers from further reading your chats. However, this should be done every time you use WhatsApp web.
• Do not leave your phone unattended when you are out.
• Lock all your apps to prevent unknown people from accessing your apps.
• Do not connect your phone to unknown Wi-Fi connections, as hackers can also use the unique MAC address to access all your WhatsApp chats.
• In case your WhatsApp has already been hacked, deactivate your account by emailing support@whatsapp.com. Your account will be automatically deleted if not accessed for 30 days.
• Enable two-step verification under your WhatsApp account settings. This will add an extra layer of security to the app.
• Lock WhatsApp. It is imperative to have the AppLocker that will help you lock your WhatsApp. While WhatsApp does not offer this application per se, you can download it and the app will facilitate the use of your WhatsApp with a password or PIN. This will help to prevent anyone who has access to your phone from accessing your WhatsApp account, since they will require a password to open it.

2015-11-11


Dr Karen Lazenby, Registrar: Systems and Administration

Dr Karen Lazenby, former Director: Client Service Centre at the University of Pretoria (UP), was appointed as Registrar: Systems and Administration at the University of the Free State (UFS) as from 1 November 2015. She will be responsible for student enrolment, administration and services, and International Affairs.

“We are extremely fortunate to have a person of the calibre and experience of Dr Lazenby to join the senior team to help us create a 21st century student-centred management system using the best technologies available. She is without question the leader in her field, and the UFS is delighted to have her as part of the Kovsie community,” says Prof Jonathan Jansen, Vice-Chancellor and Rector of the UFS.

Educational background

Dr Lazenby completed the BA (1992) and Honours (1993) degrees in English (cum laude) at the University of Potchefstroom before pursuing a Diploma in Tertiary Education (1996) and a Master's Degree in Computer Integrated Education (1998) at the University of Pretoria. She obtained a PhD in Education in 2003 on the topic ‘Technology and educational innovation: A case study of the virtual campus of the University of Pretoria’ and an Executive MBA from the University of Cape Town in 2006.

A track record to reckon with


Dr Lazenby started her career in higher education as a lecturer in Communication at the VaalTriangle Technikon in 1994, and was appointed as Head of Academic Staff Development the following year.  A year later, she joined Technikon SA as instructional designer at the Centre for Courseware Design and Development, and in 1997 she was appointed as Manager of Institutional Research. She was subsequently seconded to establish TSA Online and coordinate institutional technology. Dr Lazenby was appointed as a project manager at the department of Education Innovation at the University of Pretoria in 1998 where she implemented WebCT/Blackboard, online applications and payments, and student and lecturer portals (virtual campus). In 2000 she was appointed as Deputy Director: Electronic Education.

She was seconded by the UP Executive to establish the Client Service Centre in 2001 to provide integrated, efficient and effective services to students and other clients of the University. During her time as Director: Client Service Centre, she was inter alia, responsible for information and data governance, the intranet, website and call centre of the university, student recruitment, publications, application for study support, study finance, postgraduate scholarships, student accounts, payments, residence placement, access cards and parking, the graduate career office, and international student division. In 2005, she also acted as Director: Corporate Communication and Marketing.

Her vision for the UFS

“I would like to get the university's student administration to such a point that academic staff can focus on teaching and research. Streamlining the enrolment process so that we may see the necessary yield required in terms of our growth target as a university, is my other goal.” She added that capitalising on the strong international positioning of the UFS achieved by Prof Jansen, is a mission she intends to carry out. "I am grateful for the opportunity to work with Prof Jansen and the senior management team and am delighted to be part of the Kovsie community."

Dr Lazenby has published several articles and presented nineteen papers at international conferences.
