Though DoS attacks don't usually result in the theft or loss of data, they can cost you a great deal of time and money to handle. In each case, the DoS attack prevents customers or employees from using the service or resources they expect.ĭoS attacks often target websites of high-profile organisations such as banks, media companies and governments. This can be done by many means, either with malware, or by flooding the target network with traffic, or sending information that triggers a crash such as requesting overly complex queries that lock up a database. The previous two threats are usually exploited to breach networks and steal information, but a Denial-of-Service (DoS) attack is meant to shut down your network and make it inaccessible.
A vulnerability scanner will give you a real-time inventory of all the software which needs updating, as well as detect misconfigurations that reduce your security, so you can stay as secure as possible.
If you don't update your software, firmware and operating systems to the latest versions as they're released, you're leaving your network exposed. Applying patches to fix these vulnerabilities across an organisation's entire network of devices can be time-consuming and complex to implement - but it is essential.
Software and app developers constantly release updates with patches to cover vulnerabilities that have been discovered in their code. Either can create a serious vulnerability - for example, a misconfigured firewall can allow unauthorized access to an internal network, or a wrongly configured web server could leak sensitive information. This can happen when you change a setting without fully understanding the consequences, or when an incorrect value is entered. Misconfiguration errors occur when configuring a system or application so that it's less secure. #1 MisconfigurationĪccording to recent research by Verizon, misconfiguration errors and misuse now make up 14% of breaches. So what threats does this modern network face? While traditionally, these would all live on one "corporate network," - networks today are often just made up of the devices themselves, and how they're connected: across the internet, sometimes via VPNs, to the homes and cafes people work from, to the cloud and data centres where services live. Every organisation that needs to deliver services to their customers and employees must protect their IT 'network' - all the apps and connected devices from laptops and desktops to servers and smartphones. So, check the internet connection on your phone and then go link your device once again.Cybersecurity today matters so much because of everyone's dependence on technology, from collaboration, communication and collecting data to e-commerce and entertainment. Your phone is probably the primary device on which you use WhatsApp, and as per the feature, if your phone goes offline, after 14 days the linked devices will be logged out.
After that, re-install the beta version of the app and then open WhatsApp settings to connect linked devices and see the problem is fixed.
If you haven’t joined WhatsApp beta yet, visit the relevant pages on Play Store or on Apple’s test flight to join it. So, if your WhatsApp faces the same issue on linked devices, WhatsApp is able to automatically fix this via security update, however, you’ll have to be a beta tester.
The above-mentioned fix has been announced for WhatsApp beta testers for Android and for iOS as well. There are some other fixes you can also try if the problem still persists with your devices. Once the update is done, try linking your devices again. On your Android or iPhone, go to the respective app store, search for WhatsApp and click on update next to it, if available.
