Do tech firms in India really need a 3 month notice period?
Experts have highlighted that a three month notice period heavily costs the
company from which the candidate resigns. This is because the candidate will
have a lower level of productivity since they already have one foot out of the
door, which leads to a loss of time and resources for the company. From the
candidate’s point of view, a 3 month notice period may hinder their chance to be
hired by a new organisation as the long duration between hiring and joining
creates a level of uncertainty. ... When asked about his take on the idea of a
15 day notice period for tech companies, the CEO of NetConnect Global, Mr Sunil
Bist, said, “I think it is a great idea when you think about employee growth.
After the pandemic, we have seen an acute competition spree to hire the right
talent as soon as possible—a more extended notice period would mean losing out
on it because of time constraints. ...” In his opinion, “The current norm of a 3
months notice period in most tech companies was started with good intentions,
but what a company needs to see is whether it serves its intended
purpose.”
Tailscale: A Virtual Private Network for Zero Trust Security
Unlike traditional, hub-and-spoke VPN network architectures that send network
traffic through a central gateway, Tailscale creates a peer-to-peer mesh
network. This mesh topology connects each device to every other device directly.
A hub-and-spoke architecture is simpler than mesh, but it’s got some downsides:
higher latency for remote users, not allowing direct connections between
individual nodes, being harder to scale, and providing a single point of failure
that can break the entire network. In contrast, a peer-to-peer mesh network
results in lower latency and higher throughput and eliminates the need to
manually configure port forwarding. It also allows for connection migration:
existing connections are maintained even when switching to a different network,
such as from WiFi to wired. The idea of mesh VPNs has been around for a while,
mostly for niche uses. But the advent of cloud-based infrastructure coupled with
the rise in remote workers has made organizations take a closer look at them,

Researchers used electromagnetic signals to classify malware infecting IoT devices
The researchers proposed a novel approach of using side channel information to
identify malware targeting IoT systems. The technique could allow analysts to
determine malware type and identity, even when the malicious code is heavily
obfuscated to prevent static or symbolic binary analysis. ... The team analyzed
power side-channel signals using Convolution Neural Networks (CNN) to detect
malicious activities on IoT devices. The collected data is very noisy for this
reason the researchers needed a preprocessing step to isolate relevant
informative signals. This relevant data was used to train neural network models
and machine learning algorithms to classify malware types, binaries, obfuscation
methods, and detect the use of packers. The academics collected 3 000 traces
each for 30 malware binaries and 10 000 traces for benign activity. They
recorded 100,000 measurement traces from an IoT device that was infected by
various strains of malware and realistic benign activity.
Microsoft Sees Rampant Log4j Exploit Attempts, Testing
Most recently, Microsoft has observed attackers obfuscating the HTTP requests
made against targeted systems. Those requests generate a log using Log4j 2 that
leverages Java Naming and Directory Interface (JNDI) to perform a request to the
attacker-controlled site. The vulnerability then causes the exploited process to
reach out to the site and execute the payload. Microsoft has observed many
attacks in which the attacker-owned parameter is a DNS logging system, intended
to log a request to the site to fingerprint the vulnerable systems. The crafted
string that enables Log4Shell exploitation contains “jndi,” following by the
protocol – such as “ldap,” “ldaps” “rmi,” “dns,” “iiop,” or “http” – and then
the attacker domain. But to evade detection, attackers are mixing up the request
patterns: For example, Microsoft has seen exploit code written that runs a lower
or upper command within the exploitation string. Even more complicated
obfuscation attempts are being made to try to bypass string-matching
detections
How IPsec works, it’s components and purpose
An IPsec VPN connection starts with establishment of a Security Association (SA)
between two communicating computers, or hosts. In general, this involves the
exchange of cryptographic keys that will allow the parties to encrypt and
decrypt their communication. (For more on how cryptography works in general,
check out CSO's cryptography explainer.) The exact type of encryption used is
negotiated between the two hosts automatically and will depend on their security
goals within the CIA triad; for instance, you could encrypt messages to ensure
message integrity ... The information about the SA is passed to the IPsec module
running on each of the communicating hosts, and each host's IPsec module uses
that information to modify every IP packet sent to the other host, and to
process similarly modified packets received in return. These modifications can
affect both the packet’s header—metadata at the beginning of the packet
explaining where the packet is going, where it came from, its length, and other
information—and its payload, which is the actual data being sent.
Google makes the perfect case for why you shouldn't use Chrome
MV3 doesn't just create issues for end-users. Developers could face challenges
as well. According to the EFF: "The changes in Manifest V3 won't stop malicious
extensions but will hurt innovation, reduce extension capabilities and harm
real-world performance. Google is right to ban remotely hosted code (with some
exceptions for things like user scripts), but this is a policy change that
didn't need to be bundled with the rest of Manifest V3." The EFF is spot on.
Yes, Google should (with few exceptions) ban remote code. But releasing guidance
that breaks so much functionality for third-party extensions isn't the way to
go. And for developers, this could lead to many of them having to work with two
different code bases—one for Chrome and one for all other browsers. That's a
proposition many devs won't accept. Is it in Google's best interest to prevent
the development and usage of ad-blocking extensions? Probably not. But by
creating guidance that prevents those developers from creating non-malicious
(often helpful) addons, they are putting themselves in a rather awkward
position.
breathing.ai Founder Hannes Bend on Improving Mental Health at Work in 2022
Developed based on extensive research, the breathing.ai Chrome extension is
built on state-of-the-art machine learning that uses the webcam to detect
breathing and heart rate and when the user may need a break from the screen and
work. Based on which ones are the most calming or performance-improving,
personalized break reminders are either breath work, meditation, movement, or
simply a suggested break from the screen. The over 100 exercises include simple
short deep breathing as breathwork, body scan as meditations, shoulder rolls for
movements, or a short walk for just a break from screens. All exercises offer 20
seconds to 2 minutes short practices to build mindfulness and wellness into the
daily flow. The extension also provides soothing background sounds. ... We are
currently focused on making screens adaptive to vital signs, and our long-term
vision and patent aim to create adaptive interfaces for audio and olfactory
devices. Our interfaces, adaptive to the user’s nervous system, will be used
only for screens but also as voice assistants and other audio use cases,
personalized diffusers and other olfactory devices, personalized IoT, cars, and
all interface-based technological interactions.
Blockchain And You - How Will Blockchain Affect Your Future
Let’s look at a simple health care use case on a private blockchain. In this
scenario, patient records are the data blocks, and the transactions that update
the data blocks are the chains. This means that all patient information and any
updates made to the patient information are recorded in the data block. For
example, the data block stores prescription information and the procedures
performed on the patient. All the data on the data block is immutable and
traceable. If the data block is shared with a designated party, this transaction
is also traceable. Transferring a patient’s medical records from one hospital to
another hospital is easy and secure using blockchain. Additionally, since all
the data blocks are immutable, the patient’s records can be used automatically
as the input of future interactions. Think back to when we discussed filing
insurance claims. The information in the patient’s record, such as medications
or the procedures, could automatically trigger insurance claims. The patient no
longer needs to collect all their bills and determine which items might be
covered by their insurance policy.
Top technology trends come down to CIO strategy in 2022
Generative AI, algorithms that assess existing data, such as text, audio or
visual files, recognize the underlying pattern of that data and then replicate
the pattern to generate similar content, is a top technology trends for CIOs to
watch in 2022, Groombridge said. Generative AI can be used to discover new
products in research and development settings, he said. "There have been uses of
it to identify new medicines and it was even used to rapidly identify potential
treatments for COVID, for example," he said. On the operational side of AI,
Groombridge said it will be crucial for CIOs to pay attention to AI engineering,
a discipline focused on designing systems and applications to better utilize and
optimize AI in the enterprise. As businesses recognize AI's potential and rush
to build products, they will likely encounter a new challenge -- maintaining the
AI algorithms. As input data for models changes and as business outcomes change,
the models themselves need adjusting. Lack of maintenance can cause the AI
algorithms to eventually lose value, Groombridge said.
Howto create opportunities in the fragmented European marketplace
As the world continues to change and markets continue to develop, it is vital
for market participants to ensure they are capable of accessing the required
markets and services in a stated period of time, while they also need to be able
to move to locations where their presence is needed so as to keep ahead over
their rivals. Nonetheless, new opportunities tend to emerge from transition.
Changes allow organisations to re-evaluate their trading strategies, contemplate
utilising new third-party service providers, such as hosting and infrastructure
services, and ponder how they can increase their operatorial efficiencies as
well as improve the overall trading experience. In these uncertain times, having
access to a ready-made, up to standard trading ecosystem is both a necessity and
key differentiator for trading companies. The environment should have adaptive
on-demand connectivity which uses numerous malleable channels and solutions, not
to mention co-location services, so as connectivity can be provided to all major
hubs.
