The role of active and passive monitoring in virtual networks

Active monitoring: Also known as synthetic monitoring, involves injecting test traffic into the network, typically with the same forwarding criteria as the user traffic (service) being monitored, and then measuring its performance. These tests can either be one-way (from site ‘A’ to site ‘D’ or round trip (from site ‘A’ to site ‘D’ and back to site ‘A’), depending on what you want to measure. Since test traffic mimics the service traffic, active testing is ideal for providing a real-time view of the end-to-end performance of a service with regards to such things as latency (or delay), jitter (or delay variation), or packet loss. It’s worth noting that active testing can be performed between any 2 sites along the service path, for example, from site ‘A’ to site ‘B’ or site ’A’ to site ‘C’. This means that, with some simple math, it’s possible to segment the overall end-to-end path so that performance indicators can be derived on a per segment basis, providing greater, real-time visibility into where issues might be located. Network Troubleshooting ways

Active monitoring is the primary method for policing SLAs, since it provides a real-time view of performance.

Passive monitoring: This technique involves capturing and analyzing live network traffic, or traffic statistics, at a specific point in the network – for example, the network interface to an application server. As its name suggests, passive monitoring does not require another site in the network to be involved, or even aware. At its simplest, passive monitoring may be nothing more than the periodic collecting of port statistics, like byte and packet transmit and receive numbers. More typically, it also involves capturing some, or all, of the traffic flowing through a port for detailed, non-real-time, analysis of things like signaling protocols, application usage or top bandwidth consumers.

Nbtstat

Nbtstat (Nbtstat.Exe) is a command-line device for troubleshooting NetBIOS call resolution problems. NetBIOS is a session-layer protocol that formed the inspiration of Microsoft network applications for numerous years. NetBIOS applications pick out services on the network by means of the use of 16-character NetBIOS names. Each laptop on a community may have several one of a kind NetBIOS names to identify NetBIOS offerings on that system.

Today, NetBIOS is applied on TCP/IP networks by way of using NetBIOS over TCP/IP (NetBT). NetBT includes its own form of name decision to clear up NetBIOS names to IP addresses. Names is probably resolved by way of broadcast queries to the nearby network phase or by using queries to a WINS server. Network Troubleshooting

Unfortunately, NetBIOS name resolution is a not unusual source of problems. You can use Nbtstat to expose the NetBIOS names available on the nearby laptop or far off computers. In troubleshooting scenarios, this facilitates you to verify that a NetBIOS provider is to be had and its call is being successfully resolved.

To view the NetBIOS call cache, open a command spark off and run the following command.

Implementation Phase
Implement Strong Physical Security Controls

The loss or robbery of network device may also pose a vast danger to a wireless community due to the fact configuration of the network can be retrieved from a lost access point or wireless interface card. By securely mounting network gadget, inclusive of get entry to points, in less reachable locations collectively with robust bodily safety controls, the hazard of robbery may be minimised.

Avoid Excessive Coverage of Wireless Networks
Using the facts collected throughout the web site survey, right placement of access points can be designed to avoid immoderate coverage by the wi-fi network and consequently restriction the opportunity of intrusion. In addition to proper placement of the get admission to factors, adjusting the radio frequency (RF) energy transmission or the usage of directional antennas also can manipulate the propagation of the RF sign and subsequently manipulate coverage of a wi-fi community.

Secure Access Points
Access points are the center of a wireless network. Their security definitely has an overall impact on the security of the wireless network. Properly securing get admission to factors is step one in shielding a wireless community. The following suggestions can assist in hardening access points:

Change the default configuration settings;
Change encryption keys regularly;
Ensure that each one get admission to points have robust, precise administrative passwords and exchange the passwords regularly;
Disable all insecure and unused management protocols on access points and configure the remaining control protocols for least privilege;
Activate logging functions and direct all log entries to a far off logging server;
Enable wireless threshold parameters, consisting of inaction timeouts and most supported associations.
Use Non-suggestive Service Set Identifier (SSID) Naming Conventions
In a wi-fi network, an SSID serves as a network name for segmenting networks. A customer station should be configured with an appropriate SSID if you want to join a network. The SSID price is broadcast in beacons, probe requests and probe responses. To save you a malicious attacker from gathering reconnaissance facts on a wireless community via eavesdropping, SSIDs have to not reflect inner data of the organisation.

Disable Direct Client-to-Client "Ad-Hoc Mode" Transmissions
In general, a wi-fi community can be operated the usage of three one of a kind topologies; infrastructure mode, ad-hoc mode and bridging mode. When a wireless community operates in ad-hoc mode, consumer stations are connected directly and no get entry to point is required. Using this mode, a capability attacker can gain get entry to to a purchaser station effortlessly if the customer station is wrongly configured. Unless there is a selected business need, the ad-hoc mode should be disabled on wi-fi gadgets.

Limit Client-to-Client Communication thru the Access Point
Most established wi-fi networks function in "infrastructure" mode that requires the usage of one or greater access factors. With this configuration, all visitors in the wi-fi network travels through the get right of entry to factors. By controlling the communication among client stations at the get admission to points, malicious users can be averted from having access to vulnerable purchaser stations.

Keep Security Patches Up-to-date
Newly observed protection vulnerabilities in dealer products ought to be patched to prevent inadvertent and malicious exploits. Patches need to additionally be tested before deployment in order to make sure they work correctly. the deployment of a wireless network

Employ MAC Address Filtering on Access Points
MAC deal with filtering can be considered the primary layer of defence for wi-fi networks. With MAC cope with filtering enabled, simplest gadgets with pre-accredited MAC addresses can see the community and be granted get admission to to the network. However, such get admission to control should in no way be entirely relied upon to protect information confidentiality and integrity, as equipment are to be had at the Internet for enhancing the MAC address of a consumer. Besides, MAC deal with filtering mechanisms may not be feasible in some scenarios which includes the implementation of public wireless hotspots.

Deploy Wireless intrusion detection structures
Deploying wi-fi intrusion detection systems at the community can assist locate and reply to malicious sports in a well timed manner. More recently, some of wi-fi intrusion detection structures have been ready with skills to come across and save you rogue get entry to points.

There are plenty of reasons for organizations to embrace edge computing. By moving applications, data, and computing services to the edge of a network, as opposed to a large data center or cloud, organizations can lower operating costs, improve application performance, reduce network traffic, and achieve real-time data analytics.

As more organizations come to know the advantages of edge of network devices, many are eyeing deployments. In fact, according to the IDG 2018 State of the Network, 56% of networking professionals have plans for edge computing in their organizations.

But deployments can come with challenges. Chief among these is security: edge devices running insecure software platforms that are unpatched can cause an organization to fall victim to a cyberattack. That’s especially true in the case of Internet of Thing devices, many of which don’t have traditional IT hardware protocols.

Consider, for example, Mirai. The infamous botnet caused a nationwide outage in 2016 after waging a massive distributed denial-of-service attack using hundreds of thousands of compromised IoT devices, including personal surveillance cameras and home routers. And then there’s the deployment challenge of finding IT professionals skilled in integrating edge computing with enterprise technology. network deployments

So how can businesses optimize edge IT while ensuring devices are deployed quickly, easily, and securely?

NOC Support Engineer

A network operations center, or NOC (pronounced “knock”), is a centralized location where IT technicians directly support the efforts of remote monitoring and management (RMM) software. NOC teams are heavily utilized in the managed IT services space, and a tremendous driver of service delivery for many managed services providers (MSPs).

These technical teams keep a watchful eye over the endpoints that they monitor and manage, independently resolving issues are they arise and taking preventative steps to ensure many issues do not occur. NOC teams are also heavily involved in high-level security actions and backup and disaster recovery (BDR) efforts, ensuring 24x7x365 uptime for an MSP’s customers.
NOC Support Engineer

What are the Roles & Responsibilities of a NOC Technician?
NOC engineers and technicians are responsible for monitoring infrastructure health, security and capacity on a clients’ environment. They make decisions and adjustments to ensure optimal network performance and organizational productivity.

When any action or intervention from the MSP is required, NOC technicians can create alerts (or “tickets”) that identify and categorize the issue based on severity, alert type and other criteria. Depending on the relationship between the NOC and the MSP, technical teams can then work together to resolve the problem (and identify its root cause to prevent future issues).
