Security Risks Concerning Virtual Personal Assistants

VPA (Virtual Personal Assistant) software application follow commands of a user intelligently and performs a variety of tasks such as searching information on the web, scheduling an appointment, monitoring health data, initiating online shopping, searching for addresses & location, etc. Also known as Intelligent Personal Assistant (IPAs); Siri, Google Now, Alexa, Cortana, etc. are the most commonly used ones.

Although Virtual Personal Assistants are of great use, there are certain security risks concerning them. Here we have discussed the most prominent security threats associated with VPAs

  • Eavesdropping: A VPA is programmed to follow voice commands. So, it passively listens to everything being said, if the user forgets to turn it off when not in use. Thus, it ends up collecting user’s voice data without his knowledge. This recorded data always poses a risk of hijacking because cybercriminals might collect & use it unlawfully.
  • Vast Exposure Of Personal Information: VPAs resort to different databases on the web in order to respond to user’s query. Although it is highly convenient, it can pose a serious security threat.
  • Data Theft: VPA keeps a track of the user’s activity and stores that information on the device as well as a remote database. When an VPA hijacker gets hold of this information, he can extract the data and exploit it to offend the user.
  • Voice/Audio Hijacking: This technology recognizes voice to take commands. Even though it understands different words & their pronunciations, it does not distinguish the voices of different users. This can be used against the user, as an impersonator might command the VPA to perform tasks that may harm the user. Even if it recognizes the user’s voice, there is a possibility that a cybercriminal might use the actual user’s voice recording and issue commands to the VPA.
  • Remote Malware Downloading: A compromised VPA might be instructed to visit certain sites containing a malicious link. Once clicked, this link installs a malware in the device which continues to operate & damage the device remotely without the user’s knowledge.
  • Undertake Tasks Autonomously: Users might register automated commands with a VPA. This can be exploited by the hijacker to victimize the user.  For example, the user may direct his VPA to pay his phone bill every month. The VPA further takes the command and connects it to an authorized payment gateway. If the VPA is compromised, the hacker might dismiss the bill payment and transfer funds to his remote account.

There is no denying the fact that virtual personal assistants provide numerous benefits. However, it is important to stay cautious in order to avoid security risks.

Factors That Affect Internet Speed

Users, nowadays, enjoy numerous web enabled services for entertainment, education, business, marketing etc. Studies suggest that there were 4,100,667,287 internet users worldwide as on January 1, 2019. As internet has become an integral part of our life; so a good internet speed is of due importance.

Fast internet connection enables you to browse the web, install new programs & software, stream videos & listen to music without any snag. However, a slow internet connection on the other hand can lead to frustration.

Let us gain some insight on factors that affect internet speed:

  • Connection Type: Your internet speed significantly depends on the type of connection available. You can opt for any internet connection type such as modem, 4G wireless, hotspots, DSL, mobile satellite, fiber, cable, etc. Also, the speed of your internet connection depends largely on the technology being used by your internet service provider.
  • Network Congestion: Another reason for a slow internet speed is internet traffic. So, when large number of people are using the internet then the internet speed is bound to slow down. Also, when multiple members of your family are using the internet & hogging the bandwidth by downloading, streaming or playing games online then the internet speed might reduce. Even though, the modern network connections are designed to handle a high volume of connections, the internet speed tends to slow down during the peak hours.
  • Faulty Devices: A slow internet speed might also be a result of your faulty device. An old device with outdated program & software might not be able to support modern websites that feature lot of multimedia content. This may lead to slow buffering. Another reason of a slow connection could be presence of a malware or virus on the device.
  • Location Of Wi-Fi Router: The location of your router also makes a considerable difference on the speed of internet. Factors such as distance from the devices, height at which the router is placed above the ground, proximity to materials that may obstruct Wi-Fi signals, etc. have an impact on the speed of internet. It is always advisable to place your router at a central position away from walls & obstructions. This helps in easy transmission of the signal and reduces the distance to be travelled by it.
  • Presence Of Other Networks: There is a possibility that the internet speed might slow down because of conflicting transmissions in an area having a large number of different Wi-Fi networks.
  • Internet Plan: The speed of your internet also depends on the internet plan bought by you. Choose a plan on the basis of your need & usage as well as the number of people who would share the network connection.

Public Cloud Security

Public cloud is a computing service offered by a third party provider to users. It can be used by anyone who wants to use or purchase the cloud service. Not only does public cloud systems help in saving purchasing costs, but also reduces management & maintenance expenses for hardware & software infrastructure. A distinctive feature of using public cloud service is that many personnel can simultaneously use an application from their respective devices. Although public cloud offers infinite scalability and can be deployed faster, it is advised to take appropriate measures to prevent any security lapse. Below we have discussed certain points that can help in strengthening public cloud security for an enterprise.

  • Select The Right Apps For Public Cloud: Businesses use public cloud for all applications. However, it is advisable to diligently scrutinize & avoid using public cloud for mission-critical apps and data.
  • Add Security Layers: Since numerous users can access the content from the cloud, so it is essential to protect it. If you fail to secure the apps & data, it gives attackers an open window to attack and get access to restricted data. So, it is always advisable to encrypt the data and keep it protected. You must also add additional authentication layers like passwords & user credentials.
  • Access Control: Most organizations are opting for cloud technology as it allows employees to gain an access to data from any geographical location with the help of an active internet connection. However, with the increasing BYOD culture, the risk of data intrusion has also ascended. In a report by Forrester, 80% of security breaches involved privileged credentials. In order to avoid such scenario, it is important to have due control over data access. Make sure that you give password access to trusted employees only and minimize user account privileges. Also, access to any sensitive data stored on cloud should be limited to employees having entitled authority to utilize such data.
  • Backup Data: Data stored on public cloud is prone to numerous risks. The best way to avoid any risk is to take regular cloud backups. Having additional copies of data helps in preventing any kind of business loss & minimize business interruption.
  • Use Third Party Auditing Services: Organizations should opt for third party auditing services for enhanced security. Businesses can move the applications to public cloud followed by an audit to ensure that the security protocols match the standards promised by cloud service provider. This increases their feasibility and also enables them to move confidential information to the cloud.
  • Train Your Staff: Hacking attacks are increasing day by day. To prevent such attacks, it is advisable to train your employees about the working of public cloud. This enhances the security and reduces the chances of data loss.

What Is Endpoint Security?

Endpoint security is a methodology to protect the business network when being accessed by remote devices like smartphones, laptops, tablets & other wireless devices. It includes monitoring their status, software as well as activities.

Nowadays, employees are granted network access through the internet on their mobile devices which increases the need to focus on endpoint security. Enterprises have to work on securing the data available on their employee’s mobile device such that if the device falls into wrong hands, the data still stays protected. Security software such as antivirus, antispyware, firewall, etc. are installed on all endpoint devices as well as network servers.

Why Is It Called Endpoint Security?

Devices connected to the network are called endpoints as they are placed on edge of the network and are used by individuals to perform various tasks. Individuals connect to the central network using these endpoint devices. However, these devices may pose a security threat to the network and the strategy that is employed to secure these endpoints is thus known as endpoint security.

Why Is It Important To Ensure Endpoint Security?

  • There has been a significant increase in BYOD culture
  • There is a rise in number of employees who work from home
  • Increase in security threats via mobile devices

Ways To Implement Endpoint Security

  • User Management: Businesses should control the user access to the network. It can be done by setting up password protocols, restricting administrative privileges, usage policies, mobile device management, etc. It should be implemented in such a way that if a user loses his device then the IT team can remotely lock the device to protect the data from being compromised.
  • Encryption: Another way to keep the data safe is to implement encryption on endpoints. It is simple yet effective way to prevent the data stored on corporate devices from any risk.
  • Antivirus & Malware: In the wake of rising phishing & ransomware attacks, it is mandatory to install antivirus & malware protection software on your mobile devices. This helps in increasing endpoint security.
  • Updating & Patching: It is important to keep the devices updated. This is because devices without latest updates & patches are most vulnerable to security breaches.

Often there is a confusion between endpoint security & antivirus, although they differ from each other. The former is much wider than the latter. Antivirus protects the PCs, single or many, depending upon the type of antivirus being deployed. However, in case of endpoint security the whole network is made secure. It provides provisions for application whitelisting, endpoint detection & response, network access control, etc. unlike an antivirus software.

By implementing endpoint security solutions, businesses can exercise greater control on number & types of access points on the network.
