Local area networks (LAN and Wi-Fi) are decisive factors in the ups and downs of IT performance, alongside the computer center. But running the LAN infrastructure requires considerable staff and financial resources. T-Systems takes over this task on request and guarantees success with its SLA (service level agreement). This arrangement gives companies security and facilitates a high-performing company network IT employees can breathe a sigh of relief. With managed LAN services, T-Systems takes over all tasks around the active components of the company network. T-Systems configures ports and Wi-Fi access points. As well as this, the managed service contractor provides the necessary hard- and software, including IT services. Services like proactive monitoring and technical reporting are of course also included in the agreed all-round and care-free SLA service. Cloud services are also growing in significance. T-Systems has recognized this and offers a network solution controlle

Starting with the next major update, which is Windows 10 19H1, Microsoft is making a few changes to how Windows 10 manages disk space. Some disk space, reserved storage, will be set aside to be used by updates, apps, temporary files, and system caches. Here's how to reduce the size of the Reserved Storage. Windows 10 will reserve some disk space to ensure that critical OS functions always have access to disk space. If a user almost fills up her or his storage, several Windows and application scenarios become unreliable. For example, Windows Update may fail to download new update packages. Reserved storage solves this issue. It will be introduced automatically on devices that come with version 1903 pre-installed or those where 1903 was clean installed. How much of storage is reserved In the next major release of Windows (19H1), Microsoft anticipates that reserved storage will start at about 7GB, however the amount of reserved space will vary over time based on how you u

Physical Security You might not chart physical security on a technical diagram, but physical security policy needs to be as specific as possible and communicated broadly – especially when the policy changes. Organizations should set terms for accessing physical assets (stationary like servers or mobile like cell phones and tablets). Policy documents should be tailored to those employees that have a need to access the hardware. Non-eligible employees should be alerted by emphasizing consequences for non-compliance. Technologies that enhance physical security include RFID cards, premium locks, fingerprint reading devices, PIN pads and retinal scanners. Management may need to be advised that the company should not skimp on purchasing quality devices to enhance physical security. Not to be overlooked: Any physical protection guarding sensitive areas around servers that hold critical business data. If servers are off-site, the facility should provide documents containi

The software development security domain focuses on the systems development life cycle (SDLC) from system conception through its design, development, deployment, operation, and eventual retirement from service. Information security and privacy professionals must be involved in all phases of SDLC to ensure the overall effectiveness of security controls and that privacy concerns are addressed. The proliferation of personally-owned mobile devices (e.g, smartphones, tablets, and laptops) as well as the wide variety of vulnerable mobile apps creates a higher risk of exposing confidential and business-related information in the workplace. This can occur when such information is stored on personally-owned devices. Cyber-attacks often exploit the vulnerabilities inherent in applications and operating systems. That is why frequent updates and patches to software are necessary. Additionally, special care must be taken when developing internal Web applications that are externally acces

Technology terminology can becoming overwhelming. With complicated acronyms, proprietary names for generic technology and the sheer pace of innovation, keeping up can be tough. The language of networking is no exception. The array of terms can make even simple concepts seem complex. Understanding the difference between LAN and Ethernet is one of the first steps in separating out all the computer-speak. Definitions A local-area network, or LAN, is a network that works over a small distance, typically within one building or campus. Ethernet is a type of networking protocol used on a LAN. History Originally, networks allowed computers to communicate with each other over short distances. LANs ran on protocols such as Arcnet and Token Ring. Ethernet was developed as a more-efficient protocol to use in a LAN. Features Sending data across a wire to another computer over a LAN requires that the computer send electronic signals through a network interface onto a wire. The s

Network infrastructure devices are often easy targets for attackers. Once installed, many network devices are not maintained at the same security level as general-purpose desktops and servers. The following factors can also contribute to the vulnerability of network devices: Few network devices—especially small office/home office and residential-class routers—run antivirus, integrity-maintenance, and other security tools that help protect general-purpose hosts. Manufacturers build and distribute these network devices with exploitable services, which are enabled for ease of installation, operation, and maintenance. Owners and operators of network devices often do not change vendor default settings, harden them for operations, or perform regular patching. Internet service providers may not replace equipment on a customer’s property once the equipment is no longer supported by the manufacturer or vendor. Owners and operators often overlook network devices when they inves

Network software, which operates over a network rather than on an individual computer, may perform tasks that supplement, enable or replace end-user software. Network-based antivirus software supplements desktop antivirus software. Network messaging server software enables end-user computers to send instant messages back and forth. And server application software, such as Customer Relationship Management software, replaces end-user contact management software. All network software shares the common goal of increasing productivity and improving security for network users. Although computer networks began to emerge in the 1970s, network-based software did not begin to spread widely until personal computers became commonplace in home and office settings in the late 1980s and early 1990s. However, the advent of the visual browser for the Internet in the mid 1990s marked the true turning point for network software because it effectively changed the definition of network from a too

The National Cyber Security Centre has stated that cyber attacks, unfortunately, are on the rise. While this alone is an astonishing thought, to make matters worse, it is thought that approximately 31% of businesses do not have any experience in security awareness training nor have any plans to implement cybersecurity precautions. When beginning research into cybersecurity, many are surprised at the number of different types of attacks that can occur; no longer is it merely a case of a computer hack. The most common forms of cyber attacks on businesses are phishing, viruses and ransomware; however, there are tonnes of additional risks such as malware, credential reuse and denial-of-service. For more information on the types of cybersecurity attacks, take a look at Rapid7. Once you have familiarised yourself with the types of security risks your business faces, it is time to implement processes in which you aim to keep the risk of an attack at a minimum.

You can’t abolish your biggest mobile security risk, because it’s the people who use the mobile devices. Human nature can cause many problems: Too trusting People fall for flattery, people fall for requests for help, people fall for claimed social connections, people fall for all kinds of insincere requests, including phishing messages. This behavior isn’t limited to mobile devices, but the social nature of the devices combined with small screens make it harder to check out the bonafides of messages. As a result, users are more likely to respond to phishing messages and accidentally reveal account ids, passwords, and other sensitive data. Too scatterbrained Desktop PCs stay on the desk. Mobile devices travel with their owners, until they don’t: careless or rushed travelers can easily leave mobile devices behind in the cab, restaurant, or wherever they were being used. Once the mobile device is lost, all of the data stored on it is at risk. Too lazy Safe computing requires using strong
