Outside the office, workers turn to the tablet over the PC

Outside the office, workers turn to the tablet over the PCTablet computing is not overtaking smartphones or PCs in the enterprise, but they’re definitely carving a new business niche for themselves a survey conducted by cloud content management firm Alfresco shows. According to the data cited by GigaOM, tablets have replaced the PC as the go-to workstation for working at home and on the road.

The Alfresco study found that staff is using tablets:

  • 48% of enterprise employees are using tablets after hours at home,
  • 55% of respondents use tablets at business meetings (vs. 24% using PCs),
  • 50% are turning first to slates at conferences, compared to 13% using their laptops.

Alfresco reported that employees prefer the smartphone at more informal business functions

  • 57% using them at business lunches and
  • 51% using them in coffee shops.

But the tablet is also starting to become commonplace even in those more casual settings: 34% of respondents said they would haul out their slate at a lunch meeting, while 43% would do the same in a coffee shop.

The Alfresco data indicates that the 3-screen reality is coming true. Tablets aren’t replacing either smartphones or laptops, but are instead creating a new space in-between. The vendor says it’s pretty clear that laptops are increasingly tethered to the desk or cube, while tablets are the tool of choice on the go.

Incorporating Tablets into Enterprise Security

Incorporating Mobile Devices into Enterprise SecurityEnterprise information security hasn’t caught up with the consumerization of IT according to Lenny Zeltser in a recent article on the Lenny Zeltser on Information Security blog. The author states that the urgency with which organizations need to account for consumerization is driven by modern mobile devices such as Apple iPhones and iPads.

Enterprises are coming to terms with the idea of employees connecting to the corporate network over a VPN. Be it from personal laptops and home workstations according to the article. However, most organizations haven’t looked at the effect that the proliferation of powerful mobile devices has on enterprise security architecture.

Mobile devices sometimes have VPN-like access to the corporate network. In most cases have access to the company’s email contents, calendar, and address book. The devices are as powerful as laptops were just a few years ago. Yet, their operating system’s security has not benefited from the test of time. Tablets and mobile devices lack most of the security controls we’d expect to find in a “legacy” workstation OS.

Mr. Zeltser argues we need to understand how to model the threat vectors related to mobile devices and how to adjust the security of the enterprise architecture accordingly. The measures will probably involve:

  • Greater segmentation of the company’s network,
  • Treating any device that users interact with, whether it’s a desktop or a mobile phone, as an untrusted node,
  • Standards and tools to lock down the configuration of mobile devices,
  • Practices and technologies for managing vulnerabilities in applications and the OS of mobile devices,
  • Incident response plans that incorporate both “legacy” IT infrastructure assets and mobile devices.

BYO tablet? Three ways business is getting it all wrong

BYO tech? Three ways business is getting it all wrongSilicon.com had an article describing Three ways businesses are getting BYOD all wrong. The author claims the days of the standard work-issued laptop are numbered as businesses let staff use their own computers and gadgets in the workplace.

However, in the rush to adopt bring-your-own tech, businesses are placing too many restrictions on how personal devices can be used at work according to Anthony Vigneron, collaboration services global manager at global law firm Clifford Chance. He estimates that about 10 percent of firms’ 7,000 staff share the same device at home and work.

Mr. Vigneron described for silicon.com three ways businesses get it wrong when it comes to letting staff use personal devices at work.

Use sandboxing

Businesses are often advised to provide personal devices with secure access to corporate systems using sandboxed virtual machines. Sand-boxed machines allow remote access to corporate info via a virtual desktop that is run from the business’ data center.

He says it is better to let users access corporate data and apps from their device’s own OS. “Trying to deliver applications within a sandbox is not what users want. That’s not consumerization, that’s just another way of providing the same apps on different hardware,” he said.

People want to use the native applications. They don’t want to have to log in through some other system.” He concludes “The business should be able to control some of the applications staff use but you don’t want all those things inside another application.

Give them a choice

Mr. Vigneron argues that the line where work life ends and private life begins is becoming increasingly blurred. So it doesn’t make sense to treat them as two separate entities. By not allowing workers to merge their work and home calendars, contacts, and emails, businesses are imposing an artificial distinction on their staff. He explains, “You do want some separation … People want the choice of being able to work with the same interface.

Costs matter

Letting staff use their personal smartphone while working may seem like a good idea. However, employees might be in for an unpleasant shock when they get their phone bill. Mr. Vigneron said “For companies to allow for consumerization, the price has to get to an equivalent of what we can get as a corporate. They’re not doing that at the moment.

Tablet Security Tips

Tablet Security Tips ICSA Labs, an independent division of Verizon has provided third-party testing and certification of security products since 1989. They suggest a series of security tips for smartphone, tablet, or app user’s Help Net Security reports.

Only buy apps from recognized app stores

App storeApps from unofficial third-party stores and applications downloaded from peer-to-peer sites are much more likely to contain malware than apps sanctioned by official vendor stores such as the Android App Market or Apple App Store.

Think twice about accepting permissions

Most applications, legitimate as well as malicious ones, need users to accept several “permissions” before the apps are installed. Check carefully to be sure that the app comes from a legitimate source. I wrote about mobile phones leaking data previously.

Monitor bills for irregular charges.

Monitor billsIf attackers gain access to personal information stored on the mobile device, they can quickly rack up charges by sending “silent” text messages to high-priced call services. For example, if the Google (GOOG) Android Trojan GGTracker is inadvertently installed on a device, it can sign up users, without their knowledge, for premium text messaging services.

Employ security policies to protect employer-issued devices

Employers should enforce password-based access and require voice mail codes so that only authorized users can get access to data on employer-issued devices.

Be mindful of more personal devices at work

more personal devices at workCompanies must have security systems and policies in place to safeguard their business environment and prevent access to company networks from employees’ personal devices. I wrote about BYOT here.

Remember that a tablet is a tiny PCs

Many security threats that apply to traditional computers also apply to mobile devices, such as smartphones and tablets, and consumers should take necessary measures to protect themselves. One way to do this is to install anti-malware software on mobile devices and enable VPN functionality.

Protect your tablet, smartphone, and voicemail PIN

Protect your tablet, smartphone, and voicemail PINIf your mobile phone does not have a password, add one that is at least six digits. Try to choose a unique password that is not already used across other systems and accounts. Do not use repeating digits in passwords or voice mail pins. Remember that your provider will never request your voice mail pin, so do not be tempted to give it to anyone who requests it.

New School Year Same Security Threats

New School Year Same Security Threats Another school year is starting up and security firm WatchGuard has a list of the top threat to school IT systems as classes start up again. Eric Aarrestad, Vice President at privately held WatchGuard Technologies says, “With so much at risk and so much to gain by cybercriminals, today’s campus is one of the most dangerous IT environments around.” He continues, “Unlike enterprise organizations that can throw substantial resources towards network and data protection, schools and universities are more constrained, yet they face some of the most demanding security challenges due to the dynamic interaction between students and their school’s IT resources.”

Top threats at school

WatchGuard’s top at school threats include:

watchguard_logoSocial Networks The security firm calls social networks, the number one threat to school and university networks is social networks, such as Facebook and MySpace. Unfortunately, social networks act as an ideal platform to launch a myriad of attacks against students and departments, including spam, viruses, malware, phishing, and more. Adding to this, socially engineered attacks are often extremely successful due to the “trusted” environment that social networks create.

Malware As students and teachers use the web for educational purposes, the Seattle-based firm company says many unwittingly expose themselves to drive-by downloads or corrupted websites, which inject malicious forms of software on their computers. Once infected, they risk becoming victims of identity theft or loss of personal information via spyware and keyloggers.

Viruses Today, email remains one of the primary ways of delivering viruses. According to the release, recent surveys suggest that 27 percent of users fail to keep their antivirus signatures which may, in any case, be unable to up stop the new generation of viruses with polymorphic properties.

Botnets The privately held security firm estimates that 15 to 20 percent of all school and university computers connected to the Internet are part of a botnet. As part of a botnet, school and university systems can be used in a variety of unknown exploits, including spam delivery, denial of service attacks, click-fraud, identity theft, and more.

Phishing scams continue to get more advanced and selective, with students being specifically targeted. WatchGuard claims that phishing attacks via social networks achieve a success rate of over 70 percent.

Hacking In a recent survey of education IT professionals, 23 percent ranked student hackers as one of their greatest threats to network security.

Access Control Usage of mobile devices and wireless access to education IT resources continues to plague network administrators. As the use of mobile devices escalates, schools will face increasing challenges in managing authorized network access according to the security vendor.

WatchGuard Technologies provides a variety of Internet security software and hardware products, including firewalls, virtual private network (VPN) appliances, and anti-virus applications under the XTM, XCS, and e-Series brands.
