Service workers lack access to the DOM or cookies, putting a cap on the amount of harm a rogue service worker may cause. Yet, for interactions between service workers and the sites they manage, your app should make use of and support the postMessage interface. As a result, progressive web app development companies may prevent malicious service workers from accessing the DOM. This lessens the harm they can cause.

1. MAKE YOUR SECURITY TEAM
AWARE OF SOME COMMON
VULNERABILITIES WITH PWAs

2. Mobile devices are deeply ingrained in
almost every part of our lives, and this is
profoundly altering how we buy. Our need
for better, more interesting user interfaces,
quick page loads, quick information access,
and network independence is expanding
quickly. We can't deny the advantages that
PWAs are giving us. They offer internet
accessibility and reach, as well as the
immersive user experience that native
applications offer.

3. One must not put off progressive Web Apps
any longer; we should implement them right
away. By partnering with first like TechAhead, a
mobile app development agency, anyone can
start to significantly change the experience
they provide to their audience. The least
investments and a record-breaking time-to-
market will increase conversion rates and
eventually improve bottom-line outcomes.

4. PWA is designed to gradually improve your application. HTML is the foundation of
any web page and is the layer that may add the greatest value. It is in charge of
text and fundamental placement. Pure HTML pages would only be available in
black and white. Usually, this is enough to provide value, whether it be news, an e-
commerce product description, or updates from friends. The subsequent layers,
such as CSS style, JavaScript, push notifications, geolocalization, and so on, bring
about progressive improvement. For those that want to get an app in customers'
hands fast and economically, PWA design is the best option. Early-stage businesses
with limited resources who wish to launch an MVP app as quickly and as feasible
would benefit greatly from this architecture.

5. KNOW THE STRUCTURE OF PWAS
Instead of thinking of PWAs as a brand-new category of application, one may consider a
PWA to be a standard web application. It inclusion of the following HTML5 features: a
manifest and a single or multiple service worker(s)
The app's manifest, which is a JSON file, contains the data required to download it and
offer it to the user as if it were a native app. There are details like the PWA's name,
description, icon, and display settings. On the other side, the service worker gives a PWA
greater functionality. This JavaScript file works in the background of the website. It enables
developers to provide their PWA extra "app-like" features. Push alerts, offline browsing,
and background synchronization are just a few of the service worker features.

6. ATTACKING A PWA THROUGH
MANIFEST
Cross-site scripting assaults are a favorite tactic of online criminals when they
attempt to insert their malicious script into a target program. Attackers won't be able
to circumvent your manifest. This is because browsers only use the first occurrence
of the manifest, irrespective of how many manifests are present in the code. An
attacker might connect their manifest, though, if you haven't created a manifest for
your PWA.
Even while such an assault just affects the appearance of the app its symbol, colors, etc. it
might nonetheless harm your brand and discourage people from using your app.
Furthermore, many internet browsers follow new content security criteria that limit the
domains from which a web manifest can be retrieved. Thus it reduces the possibility of
harm caused by the manifest.

7. ATTACKING A PWA THROUGH A
SERVICE WORKER
Service workers lack access to the DOM or
cookies, putting a cap on the amount of harm a
rogue service worker may cause. Yet, for
interactions between service workers and the
sites they manage, your app should make use of
and support the postMessage interface. As a
result, progressive web app development
companies may prevent malicious service
workers from accessing the DOM. This lessens
the harm they can cause.
Service workers are a desirable target for
attacks. They enable attackers to intercept
connections or provide changed results to
consumers. An online attacker who gains
control of a service provider can continue to
target both inbound and outgoing data. The
guy in the middle attack is a particular kind of
cyberattack. Serious ramifications for your
app and users may result from a rogue
service worker.

8. BENEFITS OF SECURING TOKENS
IN PROGRESSIVE WEB APPS
Users cannot trust a PWA unless it is delivered via a secure network, especially when
there may be a financial transaction. PWA connections are more secure than those
in conventional native Apps since they are SSL encrypted by browsers.
PWAs make use of automated maintenance and browser support to give users the
best possible online experience. A very high degree of security is maintained thanks
to automatic updates and maintenance.

9. PWAs are intended to offer a satisfying, safe user
experience. Once installed, users may access PWAs
from their device just like they would a native App by
selecting the PWA icon from their home screen.
