Reading Time-approximately: 4 minutesOrganizations have used disaster recovery tiers to define the DR process for years. These key tiers can serve as a backbone to a comprehensive disaster recovery plan. By Paul Kirvan Disaster recovery focuses on the protection and restoration of IT system functions and network services, and it dates back to the 1970s. Its roots are in mainframe computing systems, and

By Brien Posey and John Hilliard VSS, also known as Volume Snapshot Service, operates at the block level of the file system and enables virtual server backup in Microsoft environments. In addition to the service itself, Windows VSS has three major components: VSS writer: Each VSS-aware application
Reading Time-approximately: 6 minutesQuality of service (QoS) refers to any technology that manages data traffic to reduce packet loss, latency and jitter on a network. QoS controls and manages network resources by setting priorities for specific types of data on the network. ByBen Lutkevich and Katherine Finnell Enterprise networks need to provide predictable and measurable services as applications — such as voice, video and delay-sensitive data — to traverse a
Reading Time-approximately: 5 minutesPKI (public key infrastructure) is the underlying framework that enables entities — users and servers — to securely exchange information using digital certificates. By TechTarget Contributor The entities that facilitate and use PKI typically involve general internet users, web clients or browsers, and company servers — though this can extend to other virtual machines (VMs) as well. The word infrastructure describes PKIs
Reading Time-approximately: < 1 minuteCHAP (Challenge-Handshake Authentication Protocol) is a more secure procedure for connecting to a system than the Password Authentication Procedure (PAP). Courtesy Post: By TechTarget Contributor Here’s how CHAP works:- After the link is made, the server sends a challenge message to the connection requestor. The requestor responds with a value obtained by using a one-way hash function. The server checks
Reading Time-approximately: 2 minutesPrivilege creep is the gradual accumulation of access rights beyond what an individual needs to do his or her job. In information technology, a privilege is an identified right that a particular end user has to a particular system resource, such as a file folder or virtual machine. By Crystal Bedell Privilege creep often occurs when an employee changes job responsibilities within the
Reading Time-approximately: 3 minutesThe principle of least privilege (POLP) is a concept in computer security that limits users’ access rights to only what are strictly required to do their jobs. Users are granted permission to read, write or execute only the files or resources necessary to do their jobs. This principle is also known as the access control principle or the principle of minimal privilege. By
Reading Time-approximately: < 1 minuteMTBF (mean time between failures) is a measure of how reliable a hardware product or component is. Courtesy Post: By TechTarget Contributor For most components, the measure is typically in thousands or even tens of thousands of hours between failures. For example, a hard disk drive may have a mean time between failures of 300,000 hours. A desired MTBF can
Reading Time-approximately: 7 minutesHigh availability (HA) is the ability of a system to operate continuously without failing for a designated period of time. HA works to ensure a system meets an agreed-upon operational performance level. In information technology (IT), a widely held but difficult-to-achieve standard of availability is known as five-nines availability, which means the system or product is available 99.999% of the time.

Reading Time-approximately: 3 minutesAt the end of last year we looked at some of ITAM’s failings. This time we explore how to improve ITAM. By Eric Chiu I believe the IT asset management (ITAM) and software asset management (SAM) community can be empowered to deliver truly valuable services to organisations around the world by addressing these challenges head on. To that end, I propose a
What is COVID-19?
On 31 December 2019, the World Health Organization (WHO) reported a cluster of pneumonia cases in Wuhan City, China. ‘Severe Acute Respiratory Syndrome Coronavirus 2’ (SARS-CoV-2) was confirmed as the causative agent of what we now know as ‘Coronavirus Disease 2019’ (COVID-19). Since then, the virus has spread to more than 100 countries, including South Africa.
